My girlfriend is unable to sign into her Minecraft account. She has tried to sign in on both the minecraft.net website and the minecraft launcher. On the minecraft.net website, the login button turns gray after pressing it, and then nothing happens. On the launcher, there is an error that says incorrect credentials.
I bought the game for her with a Minecraft gift card. After changing her password multiple times to no avail, as well as making multiple different accounts, she tried signing in on her phone and redeeming the gift card there. It worked. (I should also note that I could sign into her account on my computer on the website and on the launcher, so it only seems to be a problem with her computer.) With her unable to access it on her computer, though, I sent her the launcher setup file so she could try to sign in there (which did not work, again). She's restarted her computer multiple times and tried on different browsers. We've also waited an hour and tried again, which proved fruitless
Does anyone know what's going on? the mojang website says that we may have to wait 24 hours to try to log in again. Does this apply even though she's able to sign in on other devices besides her computer, and should we not attempt another sign-in until then? Thank you.
