I've many games in my library and have been playing them all for many many moons, until today when I set up a phone number for account recovery, Since then I can not log on on the steam app on my windows 11 pc. I can log in to the web site. I have changed my password two times. No matter what I do the steam app refuses to allow authentication. This is very annoying. I find no related help articles in searched and have no clue how to contact anyone at steam who might be able to help. Clicking any reset password link allows me to change the password for all steam web sites but i still cant log in on the local steam app. I have removed it and re-installed it. No joy. If anyone has any ideas what I may be able to do to regain access to my steam game library that would be swell.
