What is OpenSSH key format?

By default OpenSSH uses its own format specified in RFC 4716 (“The Secure Shell (SSH) Public Key File Format”. The option -t specifies the key generation algorithm (RSA in this case), while the option -b specifies the length of the key in bits. The option -f sets the name of the output file.

Which is the OpenSSH format for rsa2 key?

Export OpenSSH key: this actually exports an Open SSL encrypted private key (PKCS#1 / PEM format), which Open SSH normally uses for RSA2 key (and OpenSSH similarly uses OpenSSL formats for DSA and ECDSA private key in v2, but in recent versions has its own format for Ed25519 private key, a new algorithm OpenSSL doesn’t know about yet);

How is multi factor authentication implemented in OpenSSH?

Multi-factor authentication may be implemented with key pairs by entering a passphrase when the key pair is generated (see user key generation below). During authentication the user is prompted for the passphrase, which is used along with the presence of the private key on the SSH client to authenticate the user.
