# - SSH key asking me for a passphrase? - #

eval `ssh-agent -s`
ssh-add ~/.ssh/id_rsa
ssh-add -K ~/.ssh/id_rsa

One fix is to add the following to your ~/.ssh/config file:

# - 1. vim .ssh/config - #
# - This worked for me, paste the following text - #
Host *
   AddKeysToAgent yes
   IdentityFile ~/.ssh/id_rsa
   UseKeychain yes

Host *
   UseKeychain yes
   AddKeysToAgent yes
   IdentityFile ~/.ssh/id_rsa
   IdentityFile ~/.ssh/id_25519


# - 2. Go to create your new password in keychain: - #
How to Use Keychain to Manage Mac Passwords

a. Open finder
b. Go to Applications
c. Utilities
d. Keychain access
e. Go to Passwords
f. Add with +
g. Keychain name: uServerHome-sshPassword
h. Account Name: is_derayo
i. Password: Connecticut, Nicaragua, Guatemala, NewJersey
j. Click Add button
k. Done.



Now the agent supplies the credentials instead of me having to type in my passphrase.
