However, if you want to set up two-factor authentication by using key files and a passphrase, then type a password for the key in the Key Passphrase and Confirm Passphrase text boxes. If you are generating keys to use for automated processes, you should skip this step. You can optionally add a passphrase to the key.After a few seconds, PuTTYgen creates the key. Move the mouse around to generate random data.Confirm that the Number of bits in a generated key value is set to 2048.Under Parameters, click the SSH-2 RSA radio button.To generate and configure a key pair, follow these steps: For more information, see the next section. After you have downloaded the PuTTYgen executable to your local computer, you can use it to generate a key pair.Īlthough PuTTY and PuTTYgen work on Windows 10, as of April 2018 there are native SSH programs included in Windows 10.
