Locked out of authenticator after update to 6.3.4 and passphase was not set before

### Describe the issue

I was using authenticator with no issues during the day but, suddenly, it begun asking me for a password with the message:

> Enter password to decrypt account data.

As I had never configured a password for authenticator, I just tried and an whitespace to see if I could get in, with no luck.

I could get it working again with this procedure:

1. Manually downloaded an older version (random, 6.3.0)
2. Installed it
3. With the steps above, authenticator worked, so I
4. Set a password for it
5. Updated the plugin
6. Entered the password
7. Now it works correctly.
