[SOLVED] chromium lost saved passwords & cannot save passwords anymore

What I've done before the problem is:

(to see ssd temperature)
$ yay -S --repo nvme-cli
$ sudo nvme ...
$ sudo nvme ...
$ sudo nvme ...
...
(because os time is always reset to utc time though time zone is correct, so I tried to set time in bios)
$ sudo hwclock --hctosys
$ sudo hwclock --systohc
$ sudo hwclock --show

Now in "Password Manager/Checkup" in chormium settings, there is no saved passwords.
I also tried to save new passwords, it prompts to save passwords, and I choose to save, but still no one is saved.

Have backups…

This is often down to the used https://wiki.archlinux.org/title/Chromi … word_store - you might have been using the built-in (basic) one but now chromium is picking up some DE specific one or you have/had a desktop specific implementation that got broken and now you're using the basic one. Or you switched from one DE to another. Or the communication to the usual store doesn't function properly.

So please elaborate on the environment
Also check the system journal on whether errors related to dbus or your keyring/wallet/passex/etc show up.

Re: [SOLVED] chromium lost saved passwords & cannot save passwords anymore

UPDATE

if use a new profile, e.g.

chromium --user-data-dir=test-profile

the passwords can be saved and loaded normally,
although the error

Jan 07 09:46:02 user chromium[11630]: [11630:11653:0107/094602.042172:ERROR:net/cert/ev_root_ca_metadata.cc:160] Failed to decode OID: 0

still exists

I've deleted the old profile"~/.config/chromium/Default", no problem now, but still don't why, maybe the profile is corrupted by a bug, maybe it is hacked (this is what I don't feel safe about, backup doesn't help)

possible cause: QtWebEngine crashes for Qt 6.10.1, https://qt-project.atlassian.net/browse/QTBUG-142497

────────────────────────────────────

log when chroium should be trying to load the saved password:

Jan 07 09:46:02 user chromium[11630]: [11630:11653:0107/094602.042172:ERROR:net/cert/ev_root_ca_metadata.cc:160] Failed to decode OID: 0

Re: [SOLVED] chromium lost saved passwords & cannot save passwords anymore

"Failed to decode OID: 0" in and by itself is meaningless, QtWebEngine uses blink but chromium doesn't use QtWebEngine so QtWebEngine bugs won't affect chromium.
Are you using KDE? Can you open kwallet? Does it have a wallet w/ your chromium passwords?

Edit: after

I've deleted the old profile"~/.config/chromium/Default", no problem now

were your passwords still there?

Re: [SOLVED] chromium lost saved passwords & cannot save passwords anymore

Are you using KDE?

Yes

Can you open kwallet?

Yes

Does it have a wallet w/ your chromium passwords?

Yes, I also tried to delete the folder called "Chromium Keys" in KWalletManager,
and after saving a password, the folder will be created.

I've deleted the old profile"~/.config/chromium/Default", no problem now

were your passwords still there?

Not tested, deleted folder "Chromium Keys" in KWalletManager before deleting "~/.config/chromium/Default"
BTW, when the problem exists, I checked keys for chromium in KWalletManager, not plain text, like binary.
Now it works normally, it's plain text there, like "DJNH22wd4HtakAL6F6P0Id==".

Re: [SOLVED] chromium lost saved passwords & cannot save passwords anymore

Either you configured chromium away from kwallet or the communiation w/ kwallet failed for obscure reasons.
If this happens again you can use "dbus-monitor" to sniff their communication.

Unless and until then and please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
