Tech Tips

github and Ubuntu 22.04

github does not permit authentication via passwords, but we can use a classic token.
https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-personal-access-token-classic

Note: I already had a token, but it cannot be recalled on the web page, so generated a new token.

Create a new classic token:
Log into github https://github.com/
click on your profile photo and choose Settings

token_01

Click on Developer settings.
Click on Personal access tokens, choose classic token
Click on Generate new token and choose Generate new token (classic) Choose a name, expiration, and scope, and click on Generate token

token_02

and copy it to the clipboard or save it elsewhere.
