Where is Fedora Password Manager?

edit

I started recently to using pass for my password managing and encrypted it with my gpg key.

Now everytime I try to decrypt my passwords to copy or view it it asks for my gpg key passphrase as excepted, however it has a check box "Save in Password Manager", which will saves it forever.

I don't want to be annoyed everytime for decrypting my passwords, but I don't want to save it forever in password manager.

I want to ask where is password manager and how will it save my passphrase and how can I save it just for current login session?

I'm using GNOME.
