cant login

since a few days i needed to login via auth through browser, now the browsers just loads a white page, cant login into faf anymore

Can you try a different default browser, like Firefox, Chrome, Edge, etc.?
Do you have the box "Remember Me" ticked in the login window?

@teach_ I would suggest that you start by clearing your browser cache & trying again.

If that doesn't work, then try temporarily changing the Default Browser in Windows Settings again, clearing the cache of that browser & trying again.

Also, don't forget to click the checkbox next to Remember Me before you click the Login with Browser button so you won't have to login every time you open the client.
