Lost saved passwords (and log on cookies ?)

Description of the issue:
All was fine this morning but when i opened brave this afternoon, all the sites i usually keep logged on asked me to log in again (cookies deleted ?) and all my saved passwords have disappeared

How can this issue be reproduced?

I don’t know.

Brave Version( check About Brave): 1.50.114 (64 bits)

Additional Information:

I’ve tried to reinstall the current version without any effect


Thank you for reaching out to us.
This appears to be similar to an issue the team is working on addressing presently. Can you please tell me what happened before you opened your browser and the passwords were gone? For example, did Brave update in that time? Did you shut your machine down or put it to sleep? Etc.

Additionally, can you please confirm whether or not you’re using Windows 10 or Windows 11 at this time?

Thank you

Nothing special occured (as far as i know) between the “normal” situation when i used Brave in the morning and when i discovered the problem in the afternoon.
I didn’t shut off my PC (and it doesn’t have a “sleep” mode) and i think that the upgrade took place a few days before (from the date last modification of the subdirectory).
I use Windows 10 family (version 22H2 build 19045.2846 )
As i’m replying, i’ve noticed that brave just updated itself, i’ll check if anything has changed after sending this reply …

Edit after reloading :
I’m now running [
Version 1.50.118 Chromium: 112.0.5615.87 (Build officiel) (64 bits)
but i’m afraid that, except those i’ve created after the incident and that i’ve not lost (yet ?), my old passwords are still gone :cry:

is there any way i could try to at least export my disappeared passwords ?
If they are stored in a file (or a database) maybe an old version has been archived somewhere ?

Thank you for the information. I will pass this onto the dev team for review.

Thank you

By browsing User Data\Default\Login Data with a sqlite viewer, i’ve seen that it still contains information for my “old” credentials.
I think that my login/passwords are still there but they are not accessed anymore …
Is there any tool to recover data from this file ?

Looking into — thanks for the heads up.

Hi @Eric81 thanks for checking that! It’s good that your entries are still there. Basically, Brave (or Chrome/Chromium) look at that DB and will try to decrypt it using “OSCrypt”. This is using a key specific to your machine and if it fails to decrypt the entry, it falls back on not showing that entry in the UI.

There are a few known things which can cause the OSCrypt to fail - basically when a new key gets generated. One is when Windows users have their password forcibly reset by an admin - that will cause all OSCrypt encrypted items to get lost. I’m not 100% sure on the other cases

Did you change your password by chance recently? You might be able to change it back to what it was and that might let the browser decrypt the entries

Please let us know - and if so, give that a shot


As I’m the only user, I’ve not set any password.
Is there any other local (or distant) information used to generate the key that I could check ?
Thanks for your investigations

Hi, I am having the same issue. I am using Brave [
Version 1.47.186 Chromium: 109.0.5414.119 (Official Build) (64-bit)

It must have tried to update? I know there are no updates for Windows 7 64 bit users, and that’s what I have.
This morning, I turned on my pc, and when I opened Brave, it asked, did I want to stop message about cookies, I clicked yes. Then as I went to a web page, it didn’t have my name or password saved. I looked in my Brave Password Manager, and there was nothing.
I looked in the Log In data file, and it shows my info, but how can I get them back?

Another thing that can cause the entries to seemingly disappear would be if you copied the profile directory from another machine. Even if you’re on the same machine and do a backup/reformat your machine, it’s going to create a new key. When you have the data which was encrypted with the old key, it can’t decode it

@TornadoRider did you change password in Windows recently?

We’re looking into other scenarios trying to ID how the OS can generate a new key, which makes these entries. We’re putting all known information in NOTICE: Unexplained Data Loss Issue
