If I receive an email that has been encrypted with my public key I need the private key to be able to decrypt and read the email. The reason is with an example for encrypting/decprypting email. When it comes to ssh keys I always generate one for each device but I don't do it for my GPG keys, even though it is a bit more secure. The latter is easier but if one device is compromised so are all of the other private keys you use, because they are the same. So it's safer but also adds a bit more work and currently GitHub doesn't distinguish keys in a good way in my opinion. If you generate new ones you also need to add them to GitHub but if you lose one device it's easy to just remove the public one on GitHub.

In short you have two choices here, either you generate a new key on each of your devices or you use the same key across all of them. Git remote set-url origin this helps solving your issue.Gpgconf -kill gpg-agent Use signing with keys on multiple devices I found on the internet that using SSH instead of HTTPS as repository origin worked for some so you can try that out redirect your local repository to SSH something like this command should work: The best solution is to Uninstall your local Git and install it again (that fixed my problem somehow and i had 0 data loss with it and my repositories in both Git & SourceTree were fine)! So to keep things as short as possible, here are the solutions that worked for me (as i had that problem multliple times on multiple machines): I tried installing different versions (newer & older) of SourceTree but that didn’t work at all, google for long but didn’t work as well, i tried re-creating repositories using different methods (such as SSH) but didn’t work as well, in fact it almost caused me my changes to be lost - so i completely understand your frustration. I had similar issue, i had Bitbucket SourceTree that i used to use to manage my local Github and Bitbucket repositories, but after installing local Git i started getting Git always asking for my username and password on push.

Git in mac keeps asking for password
