Re: OAuth error when logging in

Hi Florian,

As Dave mentioned, we use the user's password as an encryption key for
saving Postgres passwords, and we do so by maintaining KeyManager. As for
OAuth implementation, you do not have a password, you need to bypass this
step ( and that is the reason you are being redirected to the login page
because of no secret key). Check the code at line no 713 in
https://github.com/FlorianJSa/pgadmin4/blob/OAuth2/web/pgadmin/__init__.py
which is causing logout for you.

Thanks,
Khushboo
