Technically Impossible

Lets look at the weak link in your statement. Anything "Technically Impossible" basically means we haven't figured out how yet.

Remedy for authentication request from Flatpuk application


Initial boot of Flatpuk application sometime requests authentication above. This authentication request says

Authentication required
The password you use to log in to your computer no longer matches that of your login keyring.

Even if you type appropriate login password, it won't accepted expectedly. Because this message means there is difference between the password used and the password stored. And it also signals corruption of keyrings.

Although this post can't show root cause and its solution, it can provide the remedy for this trouble.


As the keyring may be corrupted, it should be recreated. Its step would be

  1. Delete current keyring
  2. Regenerate new keyring

To delete keyring, issue next command. Strictly, this doesn't delete current keyring, rename it to "login.keyring.original".

cd ~/.local/share/keyrings/
cp login.keyring login.keyring.original

Run "Passwords and Keys"*1 or "GNOME Keyring"*2, new keyring file is regenerated. Then, authentication won't be requested after this.

The original keyring is not required anymore. It can be trashed with

rm ~/.local/share/keyrings/login.keyring.original
