git - Github remote permission denied

Question

I'm trying to upload my repo on github and go through all the steps upto:

git push -u origin master

at that point it gives me the following error:

remote: Permission to samrao2/manager-4.git denied to samrao1.

fatal: unable to access 'https://github.com/samrao2/manager-4.git/': The requested URL returned error: 403

I think the issue is that i was logged into another Git account before "samrao1" and now i am trying to push to "samrao2".

Can someone help me reset this to where i can successfully push to "samrao2". I am assuming i will be prompted for my password the first time i try to do it.

Unable to access https means: this has nothing to do with SSH (and switching to SSH, while possible, does not explain the original issue)

This has to do with credential caching, meaning Git will be default provide the credentials (GitHub account and password) of the old account while you are trying to push to the new account.

See if you have a credential helper that would have cached your (old account) credentials (username/password) used to authentication you.

git config credential.helper 

On Mac, as commented by Arpit J, just goto/open your keychain access->search for github.com related file->and edit credentials there.

See "Updating credentials from the OSX Keychain"

On Windows (And, in 2021, possibly Linux or even Mac), that would be the Windows Credential Managers GCMC: Git Credential Manager Core.
Open the Windows Credential Store, and see if the first user is registered there: delete that entry, and you will be able to authenticate with the second user.

(Here is an example for BitBucket)

In command-line (see git credential), for a manager core credential helper:

• Get the old password:

  printf "protocol=https
  host=github.com
  username=<me>" | 
    git credential-manager-core get
  
  # output:
  protocol=https
  host=github.com
  username=<me>
  password=<oldpassword>
  

• Remove the old password:

  printf "protocol=https
  host=github.com
  username=<me>" | 
    git credential-manager-core erase
  

(Replace <me> by your GitHub user account name)
