NOTICE: Unexplained Data Loss Issue

I just lost all my passwords. What happened? How to fix?

Brave 1.80.120
Chromium: 138.0.7204.101
Windows 11, version 24H2

After rebooting my machine and launching Brave, all saved passwords are lost except one. No error or warning message was displayed by Brave. Last Brave update was ~ 20 days ago so it seems unrelated. This is the second time in a year this happens.

OS: Manjaro Linux 26.0.1

Brave 1.86.139 (Official Build) (64-bit)

Chromium: 144.0.7559.59

Apparently Brave did crash ? Crash ID : 17ac0200-4c9f-390f-0000-000000000000
Only passwords were lost.

I have noticed that under ~/.config/BraveSoftware/Brave-Browser, I have 2 symbolic links (SingletonCookie, SingletonLock) that are broken. Probably unrelated.

I do not use a password manager extension nor brave sync.

All lost logins/passwords are present in the Login Data SQLite database, so I suppose storage key was changed for any reason.

okay, passwords just came back after another reboot … so weird

OS: Windows 11, version 25H2

Brave 1.87.188 (Official Build) (x64)

Chromium: 145.0.7632.76

This happened after my device encountered an unexpected restart, and after rebooting I noticed that all my shortcuts on my taskbar were broken. I used a system restore point to go back before this happened and it all seemed okay, until I tried to open my applications in which I was logged out of all of them including my browsers.

[Before using a restore point, I checked my /appdata/roaming folder and saw that it had barely any folders within it]

Brave begun crashing after using a restore point

But from what I remember, the password data wasn’t being read even before restoring.

In terms of Brave, the only thing that was lost were the cookies, and the passwords not being decrypted.

No 3rd party password manager, and I’m not using Brave Sync.

I looked at the Login Data folder, and in which I saw the old emails and sites were intact but I was unable to view the passwords. I do have histograms to share.

On boot everything was fine, then my computer restarted after leaving it on idle. Logging back in things were missing from appdata folders, breaking shortcuts and many more things. Prior to using a restore point, ALL of my browsers were affected. Having passwords, history, and bookmarks wiped, EXCEPT for brave, which retained everything but password info (kept my active tabs saved too).

Hello,

I’m having the same issues I had back in 2024.

ALL my saved passwords are gone from my Brave list.

What do I do next now please?

Thanks!

Hello,

If I’ve duplicated this, please forgive me. I’m desperate to regain all my passwords that were saved under Brave password manager. As in 2024, I’m having the issue again which you then mentioned that a fix was on the way.
Since this morning, 08/31/26, I’ve lost my passwords and haven’t done anything different or downloaded any app, etc. to disrupt Brave.
Please help.
Thanks!!

This issue is still happening. Just happened to me and is incredibly frustrating to say the least. Happened when I started the browser on 8/31/26, passwords were present the last time I used my computer which was 8/20/26.

I’ve made no changes or updates to my computer or windows, just opened the browser and all my settings reverted to default and passwords wiped, however all my bookmarks are still present.

I don’t use brave profiles or sync, my profile is just named Default.

My “Login Data” shows data but is all still encrypted so it’s essentially useless for the time being.

I’ve also used the solution of trying to manually run the program and profile through command prompt with no luck.

I’ve tried to uninstall and reinstall an older version of Brave from the GitHub repo from 2 weeks ago, with also no luck.
