2nd disclaimer: English is not my main language so i'm truly sorry if there are any mistakes.
Okay so I know there is a really low chance of anyone answering but here I go: I try to log in with the steam app and it tells me that the password or the username is incorrect (And obviously I type them correctly, believe me). So I try to log in from the website but even then it doesn't work!! It just tells me the same thing! And of course because of that I cannot change my password nor my username. So I tried to log in with my email address, didn't work. So I tried with my steam name, didn't work either... At this point I really gave up and decided searching on google but everytime i thought someone had the same problem I read "I cannot log in from the app but i can log in from the steam website". Of course I saw some people saying that "some apps could be interfering with steam" but it worked just fine until 17 / 5 P.M. and I swear I didn't download anything today! Except Garry's Mod but it worked just fine! (plus it's on steam so i wouldn't know why it's interfering with it).
PLEASE HELP!!!
