Where does Remmina store the encrypted password?

I have a Remmina connection with a saved password. I need that password for an other connection but I forgot it, so I would like to take it from the existing connection.

I'm well aware of: How to extract saved password from Remmina? however all the answers appear to be outdated.

My Remmina is version 1.4.2 and this is what I find when I try to search for the encrypted password in my configuration files:

$ grep -ir 'password' ./.local/share/remmina/*
./.local/share/remmina/group_rdp_xxxx.remmina:password=.
./.local/share/remmina/group_rdp_xxxx.remmina:ssh_tunnel_password=
./.local/share/remmina/group_rdp_xxxx.remmina:gateway_password=
./.local/share/remmina/group_rdp_xxxx.remmina:disablepasswordstoring=0
./.local/share/remmina/group_rdp_xxxx.remmina:password=.
./.local/share/remmina/group_rdp_xxxx.remmina:ssh_tunnel_password=
./.local/share/remmina/group_rdp_xxxx.remmina:gateway_password=
./.local/share/remmina/group_rdp_xxxx.remmina:disablepasswordstoring=0
./.local/share/remmina/group_rdp_xxxx.remmina:password=
./.local/share/remmina/group_rdp_xxxx.remmina:ssh_tunnel_password=
./.local/share/remmina/group_rdp_xxxx.remmina:gateway_password=
./.local/share/remmina/group_rdp_xxxx.remmina:disablepasswordstoring=0
./.local/share/remmina/group_vnc_yyyy.remmina:password=.
./.local/share/remmina/group_vnc_yyyy.remmina:disablepasswordstoring=0
./.local/share/remmina/group_vnc_yyyy.remmina:ssh_tunnel_password=

(Bolded lines are the ones for the connection with the saved password that works).

As you can see there is no trace of an encrypted password. All answers to the question linked above assume I'd find password=YW5zd2VycyBvdXRkYXRlZCE= in one of these files!

I use Kubuntu but Remmina is not using kwallet (I just disabled it and I can still use the yyyy connection which is the one with the password stored).

So where the heck does Remmina store said encrypted password? I already found the secret, so once I have the encrypted password it's easy to get the password back... but without finding the encrypted password it's impossible.

In Ubuntu 20.04, under Gnome, Remmina stores it's passwords in the GnuPG Keyring app.

From there you can retrieve them as clear text.
