If you are getting unverified tag in your github account when you commit using ssh from your local machine, then following instructions might help. Firstly check if you have .gitconfig file in your home directory. If you don't have it you need to create one. You can do it terminal using the below command.

touch $HOME/.gitconfig

After creating the file, you need to add your signinkey and email to your .gitconfig. You can do that in one of two way:

1. Through terminal
2. Editing the .gitconfig file

Through terminal

• Add your public SSH key to the signinkey, make sure that you use the same key that you use for your github account. Replace SSH_KEY with your pubic key

git config user.signinkey = YOUR_SSH_PUBLIC_KEY

• Add your email as well

git config user.signinkey = EMAIL

Edit the .gitconfig file

Paste the following content and replace YOUR_NAME, YOUR_EMAIL and SSH_KEY.

# .gitconfig
[user]
email = YOUR_EMAIL
name = YOUR_NAME
signingkey = SSH_KEY

Confirm that you added both signinkey and email by entering the below command in the terminal. This command will the contents of your .gitconfig.

git config --list

You are good to go
