Working on a project using untrusted computer

I have a private project (hosted on and i want to work on it from a computer that can’t be trusted. So it’s unsafe to login using my account. Is there some way to create a read only access token. Or maybe some other way to do it without creating another account. I want to be able to clone a repository and request changes, so that i can later approve them from a trusted pc.

Hello, make the project private,create a second account and add the second account as developer.
