[BUG] ProtonVPN CLI login successfull with FreeVPN Username

[cosmicflutterfish]

I am not sure if this was because I reinstalled the CLI and some key was stored or something, but when I entered protonvpn-cli login [freevpn-username] it logged me into the program without even asking for my password. I sadly didn't check if I could connect to servers before I logged out and tried it again, but yes that is all.

No Idea how to reproduce it, when I did the same thing it, I also was confused how to do the init but that's not necessary anymore? Anyway it works with email and PW now so that's good

Desktop (please complete the following information):

• Ubuntu 20.04
• Python Version: 3.8.5
• ProtonVPN-CLI Version: 3.1.0

=> btw this from the issue prompt doesnt work as it shoud be protonvpn-cli --version

• ProtonVPN-CLI Version: [e.g. 2.0.0 (protonvpn --version)]
