192.168.1.1 The login password has not been changed but an error message appears? After scrolling through the browser, I finally realized that autofill has been tricking me.

This matter has held me back for half a year. On the TP-LINK XDR3030 at home, after setting the management password, I never manually typed it once - every time I entered 192.168.1.1 , the password box will fill up by itself, click login to enter. Until that night last month, there was something wrong with the network at home. I took out my phone and wanted to check the backend. The login box popped up. I typed the password from memory and it said it was wrong. Knocked again, still wrong.

At that moment, my heart skipped a beat: Has the password been changed? The router at home has been tampered with. I am The router was hacked I wrote about how scary it was. After two nights of struggling, I figured out that not a single word in the password had been changed. It was the browser itself that had tricked me. This article explains the whole story clearly. If you also encounter "cannot log in even though the password has not been changed", just follow the steps and it will most likely be solved in ten minutes without touching a single line of reset.

Let’s first distinguish between two types of “password errors”, which are completely different in nature.

Take a minute to check the numbers before starting to check. This step saves time. The first type: An error message is reported when typing the password manually, but the automatic filling in on the computer can proceed. . That's what I did that night - I typed something wrong manually on my phone, went back to my computer and clicked on the login box, filled in the password myself, and it worked as soon as I logged in. This is the best solution. The password has not been lost or changed. The version in your memory is wrong, and the key is still in the browser's hand.

The second type: Manual typing will report an error, and automatic filling will also report an error. . The password box on the computer is automatically filled in as usual. When you click login, red text pops up. This is more troublesome because the password you filled in and saved has become invalid—either you or a family member has changed the password and forgotten to update it, or the machine has been tampered with. The dividing line between the two is just one sentence: Find a device that has never saved the password for this router and manually type the password in your memory. . Being able to enter is the first type ； Not being able to enter is the second type. I tried it on my wife's mobile phone. She had never logged into this router before, and she was logged in with just one tap - the password had not changed, and the version in my memory was wrong.

Don't underestimate this step. For those who just jumped over and made trouble, three out of ten people went around until dawn, took out a paperclip and stabbed the reset, and the broadband account, WiFi password, and port mapping were all cleared. Afterwards, they found out that it was just a ten-minute incident, which was very unfair. The full cost of reset is for me In the article about restarting and resetting The accounts have been calculated, and if you can do it without touching it, don’t touch it.

The first situation: The key is in the browser's hand, just turn it out

Confirm that the password has not been changed, and the answer will be in the browser. On the computer Chrome, go to Settings → Autofill → Password Manager. Scroll down the list and search for "192". That record is usually called this name. Click the little eye on the right, go through the Windows PIN or fingerprint, and the original password will appear - lying there in plain sight, it is ten times more reliable than your memory.

The moment I dug it out, I realized where I was wrong.: What I have in my memory is the version that starts with a capital letter and adds the year. The actual password starts with a capital letter but is followed by a bunch of random words. When I set the password, I typed it casually to make it easy to remember. As time went by, my mind automatically "rationalized" it into another string. This kind of memory drift is very common. I'm not the only one who has a bad brain. For Edge, go to Settings → Profile → Password, and for Firefox, go to Settings → Password. The names of domestic browsers are a bit confusing, but you can basically find them by clicking on the menus with the word "password" in the settings.

There is another storage method on the mobile phone. Apple's Safari password is not in the browser. It is in System Settings → Password. Go to Face ID Verification and search 192. The record is in the list. Android Chrome is Settings → Password Management. Don't be in a hurry to close it after you turn it out. Copy a memo on the spot and put a note in the weak current box . This note is a false statement, but outsiders cannot touch your home's weak current box, which is more secure than any cloud. What happened in these three minutes, I later The article about changing mobile phones and finding passwords I have also said it before - retrieving your password once is tiring, don't let yourself retrieve it a second time.

Second case: The filling also fails, first suspect these four holes.

Neither manual typing nor automatic filling can match the password. The password is really invalid. Don’t think about “getting hacked” first, check these four openings one by one, from the most common to the bottom.

The first one is the most unfair. My colleague's house is: His wife used her mobile phone to change the WiFi password and also changed the management password without telling him. The old one is still saved in his computer, and the new half is saved in the mobile browser (half of it was changed but not all of it is saved). The two devices each hold different versions of the old password, and no one can log in. In the end, the daughter-in-law untied it after she remembered it. This matter is The article about being disconnected after changing the password I’ve already written about half of it. What I’m talking about over there is WiFi passwords. The same principle applies to managing passwords.—— The moment the change was completed, all the places where the password had been stored in the whole family became old accounts. , they have to be cleared one by one.

The fourth opening needs to be discussed separately because it will disguise itself as the first three. Many routers will be temporarily locked for a few minutes if you make a mistake three or five times. While locked, you will get an error even if you make a mistake correctly. The more anxious you are, the more you click, and the more you click, the more locked you become. It looks like "the password is never correct." discriminant: Put down your phone, make a cup of tea, and try again in ten minutes. If you can get in, it's locked ； If you still report an error, it is really invalid. The lockdown duration and response sequence of each company, I am here The article was locked due to incorrect input I have measured them one by one in the article, and that article also teaches a trick "How to lose right the first time". Anyone who has been locked out should read it.

When it comes to collusion, families with two cats are most likely to fall prey to it.

It’s worth talking about the cross-section, because more people are on it than expected, and the symptoms are the most confusing. My optical modem and router are two backends: optical modem 192.168.1.1 , the router was changed by me to 192.168.2.1 Avoided the fight with the same housemates - this matter The article about two machines with the same IP It has been written in detail here that fighting with IP is another matter. What we are talking about here is tampering.

How did the crosstalk happen?: The browser stores passwords according to the URL, but the way it recognizes the URL is not as accurate as you think. Have you logged in 192.168.1.1 (optical modem), also climbed 192.168.1.1 (Router, the old address before changing the network segment), there are two records in the password manager that are almost the same. The next time you enter the backend, the one it automatically fills in may be the password of the optical modem, or it may be the old password of the router, depending on its mood. Click login and report an error. You thought your password had been changed. I suspected that a hacker had entered my home for a while. I dug it out and found that three records starting with "192.168.

The solution is to clean up: Search for 192 in the password manager, look up all the entries, and confirm which device each entry corresponds to. Machines that have been retired long ago, records deleted ； If you are in active service, please check the website address and remarks clearly. After deleting it, the login box will be automatically filled in, and the only one filled in will be no more cramps. By the way, the optical modem backend and the router background are two completely different password systems. The installation master left the optical modem super secret, the router's management password, and the broadband dial-up account. Don't mix these three things together. How to change the three passwords There is a comparison table, you can look it up when you can't tell the difference.

Confirm password is really lost: Earn money from small to large according to the price

After all the first four slots have been cleared, the password cannot be retrieved, so don’t reset it directly. There is a mature route to fishing for passwords. The article about changing mobile phones and finding passwords Wrote the full version: First, check the old device (whose phone has logged in before), then check the browser cloud synchronization (you may have a copy of your Chrome account and Apple keychain), and then ask if the app bound to the router recognizes you. If all fails, you will consider resetting. People around me who have tried it have basically gotten it back by the second stop. I can count the number of people who have actually gone to the reset step on one hand.

When it comes to reset, copy three things before doing it: Broadband account password, IPTV connection parameters, and the location of the network cable plugged into the router. After copying, stab again, after stabbing, press The article about redialing after reset The order to restore the network was restored. The broadband account at the Optical Mode registration level was not moved. What was changed was the dial-up and WiFi configuration at the router level. If you follow this for half an hour, you can restore everything. People who have the habit of configuring backups will have less trouble. Configuration backup article Import the saved bin file back, and the password will go directly back to the day of the backup - but if the backup is earlier than the day when the password was changed, the old password will still be imported. This has actually been foreshadowed in the cross-talk section above.

wrap up: Where should I write down the password? My native method

After struggling with this matter, I made a small adjustment and share it with you. I no longer rely on any place to remember my router password automatically. ——There is no browser password library (if you save it, it will remember it for you, and your brain will not remember it at all. That day it had a seizure and you were blinded at the same time), and it is not attached to the fuselage (people at home can see it). My native method is to make two copies: There is one copy in the memo and one copy of the note on the weak current box. They are located a little away so that outsiders cannot touch them. You can't lose something like managing passwords twice a year. Precisely because you lose less, you need to put it in a stable place instead of relying on muscle memory.

At the end, give a sequential summary. Follow this to avoid detours.: First find a device that has no saved password and type it manually to distinguish between the two situations. ； The first method is to directly copy the browser password library. ； The second type is to check according to the four families, focusing on whether anyone has changed the password and whether it has been temporarily locked. ； If you can’t find it after arranging everything, take the retrieval route. ； reset is always the last option . If I had done the first step that night, I would have saved an hour of fussing. The browser remembering passwords for you is a double-edged sword. It’s really convenient when it’s convenient. It doesn’t even say hello when it tries to trick you – do you know where the copy it saves for you in the password manager is? If you don’t know, go look for it tonight and don’t wait until you can’t climb it to remember it.
