[CodeTappert]

What are the changes the user will see?

On Beta it will show "Beta" next to "Login" on the login screen
See local PR here:

Why am I making these changes?

Sangara asked me to. Probably to know easier if screenshots of login pages are from beta or not

What are the changes from a developer perspective?

we create a new local key and all it based on the the server URL

Screenshots/Videos

TBD (need locales still)

How to test the changes?

???

• Play local, should not be there
• Should be there once its on beta. (you could try to change the code to your own server url to see if it appears i guess)
