~/.ssh/authorized keys

• Configure OpenSSH to allow Public-key authentication

AUTHORIZED_KEYS FILE FORMAT
     AuthorizedKeysFile specifies the files containing public keys for public key authentication; if this option is not specified, the default is ~/.ssh/authorized_keys and
     ~/.ssh/authorized_keys2.  Each line of the file contains one key (empty lines and lines starting with a ‘#’ are ignored as comments).  Public keys consist of the following
     space-separated fields: options, keytype, base64-encoded key, comment.  The options field is optional.  The supported key types are:

           [email protected]
           ecdsa-sha2-nistp256
           ecdsa-sha2-nistp384
           ecdsa-sha2-nistp521
           [email protected]
           ssh-ed25519
           ssh-dss
           ssh-rsa

     The comment field is not used for anything (but may be convenient for the user to identify the key).
