Unable to Sign In on Desktop App

I have correctly entered my username and password into the desktop app, but it keeps telling “Incorrect User Id or password”.
Please help me.

Hey there,

I’m afraid that’s not an issue I can help you with. I recommend taking a look at Google’s support page for issues with usernames and passwords.

Good luck!
