Aug 10, 2018 Public SSH keys have extension and private keys have no extension. The default SSH public and private key names on a MacBook are and idrsa. If you don’t see any keys in your SSH directory, then you can run the ssh-keygen command to generate one. You’ll be asked to enter a file name for the key pair. If you just hit the Enter key when prompted for a file name, the names of your private and public SSH key names will default to idrsa and 11 hours ago  The best encryption software to protect your data and your business.

I recently upgraded my MacOS Sierra and now ssh command keep asking for passphrase as follows when I try to login to my remote Linux/Unix server:
Enter passphrase for key ‘/Users/vivek/.ssh/id_ed25519’:
How do I fix MacOS Sierra upgrade that keep breaking ssh keys in terminal?
Generated My MacOS used to remember the ssh passphrase, but now it is asking it to me each time when I try to login to local FreeBSD nas server or remote Ubuntu server when I type:
$ ssh [email protected]
$ ssh [email protected]

Let us see Macbook delete generated rsa keys in windows 10how to fix the MacOS sierra upgrade breaking my SSH keys using various methods.

Method #1: Fix when macOS keeps asking ssh passphrase after updated to Sierra or after reboots

You need to use the UseKeychain option in your ~/.ssh/config file. From the ssh_config man page:

On macOS, specifies whether the system should search for passphrases in the user’s keychain when attempting to use a particular key. When the passphrase is provided by the user, this option also specifies whether the passphrase should be stored into the keychain once it has been verified to be correct. The argument must be yes or no. The default is no.

This is the easiest and recommended solution for all users. Edit your ~/.ssh/config file:
$ vi ~/.ssh/config
Append the following line in Host * section:

Here is my sample file:

Save and close the file. This should force ssh to remember user’s key in the keychain:
$ ssh [email protected]
$ ssh [email protected]

Method #2: Use ssh-agent/ssh-add to add all known keys to the SSH agent

The syntax is as follows to use SSH Keys on a Linux / Unix / MacOS System:

Method #3: Use keychain

OpenSSH offers RSA and DSA authentication to remote systems without supplying a password. keychain is a special bash script designed to make key-based authentication incredibly convenient and flexible. It offers various security benefits over passphrase-free keys.

Install the keychain as follows:
