What are some alternatives to SSH keys for secure access?

There are several alternatives to SSH keys, including password-based authentication, certificate-based authentication, and using hardware tokens.

Can you explain how certificate-based authentication works?

Sure! Certificate-based authentication uses digital certificates to verify the identity of users or devices, ensuring secure access.

What are hardware tokens, and how do they enhance security?

Hardware tokens are physical devices that generate one-time passwords or store cryptographic keys, adding an extra layer of security.

Are there any drawbacks to using these alternatives?

Yes, alternatives like password-based authentication can be less secure if passwords are weak, and hardware tokens can be lost or damaged.
