Retrieve Remmina Passwords

By some reason, all my remmina client configurations have a "password" attribute equal to "." (a single dot). Searching and reading I found someone suggesting secret-tool search. I tried but only returned one password. But realized that the secret-tool has an "--all" option. Then tried this and got all remmina clients information including their passwords:

secret-tool search --all key password
