devel0@tuf:~/.ssh$ ssh -T [email protected] 
Hi devel0! You've successfully authenticated, but GitHub does not provide shell access.

• test DENY

⚠️ ssh-add -D will remove cached ssh agent keys

mv ~/.ssh/github.id_rsa ~/.ssh/github.id_rsa.disabled
ssh-add -D

now a login ty

devel0@tuf:~/.ssh$ ssh -T [email protected]  
sign_and_send_pubkey: signing failed for RSA "/home/devel0/.ssh/github.id_rsa" from agent: agent refused operation
[email protected]: Permission denied (publickey).

then restore valid key

mv ~/.ssh/github.id_rsa.disabled ~/.ssh/github.id_rsa
