Passwords are not saved
On some postmarketos installation, no keyring is created by default. This can be solved by downloading thepackage from alpine repos, pressing File > New > Password Keyring, and naming it login. You may have to use seahorse to unlock the keychain on each reboot, if your UI does not support unlocking keychains.
