Recently, I sign up for a free plan on Github.com. I follow their instructions to generate a ssh key to add to my account. However, when I try ssh -v [email protected], I get this error:
debug1: Server accepts key: pkalg ssh-rsa blen 277 Agent admitted failure to sign using the key. debug1: Trying private key: /home/phuongnd08/.ssh/identity debug1: Trying private key: /home/phuongnd08/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). When I look into the error, I see a funny thing here, that is the .ssh/id_rsa was not tried, just .ssh/identity and .ssh/id_dsa were tried.
How can I fix this error? Thanks

Install GitHub CLI on macOS, Windows, or Linux. In the command line, enter gh auth login , then follow the prompts. When prompted for your preferred protocol for Git operations, select HTTPS . When asked if you would like to authenticate to Git with your GitHub credentials, enter Y .
Use your username as usual. Usually, the “Authentication Failed” error happens if you recently enabled 2-Factor Authentication on your GitHub account and uses HTTPS to push/pull in Git at the same time. GitHub deprecates the password authentication method from August 13, 2021 to favor more secure way of authentication.
You can use ssh-add ~/.ssh/id_rsa to fix this.

Check the file permissions on your key. If they are too liberal it may be refusing to use the key. Make sure they only have perssion for you (0700).
