Replace GitHub personal access token with a simple password
GitHub has announced plans to disable account passwords when authenticating Git operations such as git clone and git push. Beginning August 13, 2021, GitHub will require token-based authentication. The following script aims to restore the password authentication functionality (though it requires a one-time setup) for users who want to operate business as usual:
Encoding your GitHub token
Encode your personal access token by running the following script. The script depends on the OpenSSL package which you may need to install through apt or other package managers.
#!/usr/bin/env bash echo -n "Token: " read -s token echo echo -n "Enter password: " read -s password1 echo echo -n "Retype password: " read -s password2 echo if [[ "$password1" == "$password2" ]]; then echo -n "Encrypted token: " echo $token | openssl aes-256-cbc -pbkdf2 -a -salt -pass pass:$password1 else echo "Password does not match!" fi
Make sure that your token has been properly encoded by checking whether decoding the encrypted token recovers the original token with the following script:
#!/usr/bin/env bash echo -n "Encrypted token: " read secret echo -n "Password: " read -s password echo echo -n "Token: " echo $secret | openssl aes-256-cbc -pbkdf2 -d -a -pass pass:$password
Now you can replace your encryted token in the following script and run the script. The script automatically sets up environment variables GIT_ASKPASS and GIT_TOKEN for the current terminal session. You will be prompted to enter the password you used to encode your token. Then you can run GitHub operations from the terminal as usual!
#!/usr/bin/env bash secret=<your encryted github token goes here> echo -n "Password: " read -s password echo token=`echo $secret | openssl aes-256-cbc -pbkdf2 -d -a -pass pass:$password` echo 'echo $GIT_TOKEN' > $HOME/.git-askpass chmod +x $HOME/.git-askpass export GIT_TOKEN=$token export GIT_ASKPASS=$HOME/.git-askpass
Create a bash alias
For easy access, assign a shortcut command for the github-setup.sh script with bash alias. Look for the .bash_aliases file in your home directory. If it doesn’t exist, make a empty file. Append the following line to the file:
alias gitoken='source /<base directory to the script>/github-setup.sh'
Now you can enter the command gitoken from anywhere in the terminal to run the script. You can replace the alias gitoken with an alias of your liking.
