How to change / update keyring/lock screen passwords in AppVMs, and enable full dark mode

Hello everyone,I have been using Qubes OS for one and half year, but there are still two things I don’t know how to do.
1- How to update/change the keyring password for an AppVM, as well as how to change the lock screen password.
2- How to change the entire desktop environment theme to dark mode (including dom0 and AppVMs).

Could someone please explain the steps for these? Thank you very much in advance!

The user is created during installation:

Create your user account

Select “User Creation” to create your user account. This is what you’ll use to log in after disk decryption and when unlocking the screen locker. This is a purely local, offline account in dom0.

So sudo passwd <your-user-here> in dom0 will do.

Install and start seahorse. Right click on the keyring and select “change password”.

…or simply passwd

It’s a bit much to have to ask root to change our own password (unless we’ve forgotten it :slight_smile:

Thank you!

That works.

here I didn’t see any option for dark mode.

Install and start seahorse. Right click on the keyring and select “change password”.

For this, if you know an alternative way to change the keyring password, please let me know. I’m hesitant to install a second password manager on my device.
