I opened my Steam account on a public windows computer (gaming center). Now every time I open Steam it asks for password. I’ve tried also on my laptop (manjaro) and it does the same thing.
It drives me crazy because I have two-factor auth. Does anyone have the same issue?
Login to your steam account using a browser, not the steam client.
Change your password via that browser session.
Remove authorisation from all other devices, as mentioned above.
Keep this browser open.
Login using the Steam client, using a checkmarked “remember my password”.
When successfully loged-in using Steam client, you can close the browser session.
(Else you still have the browser session open with access to your steam account to fix things if needed…)
