How to end a github session on a remote machine?

Question

GitHub

Please help, I forgot to press the "logout" button in github on a computer that I will access ~ in a year (however, other users will have direct access to it).
How do I end that (or all) github sessions?

Answer 1

change password and keys?

Answer 2

I know this sounds silly, but if I were you, I would first ask the most trusted user left on the computer to remove cookies, cache, etc from all browsers on this computer.
