When I push to my repo, I receive an error

why this error occur when i want to push my documents.
Permission to asjadhasanjim/blood_donation.git denied to AsjadHasan. fatal: unable to access ‘https://github.com/asjadhasanjim/blood_donation.git/’: The requested URL returned error: 403

:wave: Welcome!

From that error message it looks as though you are using login credentials from an account called AsjadHasan. but the repository belongs to asjadhasanjim. Is that what you meant to do?

If you want to be able to push from a different account to your repository, you will have to add that account as a collaborator.

If that’s not what you want, you’ll need to change which account you’re logging into.
