Disable password caching for two factor authentication

We've set up our postgres to use two factor authentication of normal users
(password+otp via pam).
But this makes pgAdmin pretty much unusable because it caches the password
once connected and reuses the cached password for every additional
connection to the same server.

I am able to connect to the the server, but I'm not able to select a
different database (not a major issue), but I'm also not able to open the
SQL window.

Is there a way to disable this password caching and prompt every time a new
connection is opened to the server?
