Add password astericks when the auth token is saved

[SteadyCadence]

The URL and username are saved when the auth token is saved. We should be consistent and have the password also filled in with astericks. That removes confusion from users.

I will also work on updating the wording so that it is more clear.

I don't think filled in password is a good idea for security purpose, we didn't store the password, we just store the username. We could add the asterick.

@dimasciput Agreed; we should not be storing or caching user passwords anywhere.

[SteadyCadence]

I agree. Let's just put in 10 astericks or something.

In other news, I like the greyed out fields when the username and password are stored. Looks great!
