SFTP Auth Method Checker

Discover which authentication methods an SFTP/SSH server accepts — password, public key, keyboard-interactive, and more. No credentials required.

Common SSH authentication methods

password

Standard username/password authentication. Simple but less secure than key-based methods.

publickey

SSH key pair authentication. The most secure and recommended method for automated workflows.

keyboard-interactive

Challenge-response authentication. Often used for multi-factor authentication (MFA/2FA) or custom login prompts.

none

Server allows login without any credentials. This is a security risk and should be disabled.
