SAML SSO Error: Authentication method doesn't match requested

When logging in to Semgrep using SAML single-sign on (SSO), you may see the error Authentication method doesn't match requested:

SAML auth method error

This error only occurs when starting sign-in from Semgrep. To prevent the error, start your sign-in from your IdP (SSO provider).

To fix this problem, you must be an admin in Semgrep AppSec Platform.

  1. Sign in to Semgrep AppSec Platform.
  2. Click Settings > Access > SSO.
  3. Check the box labeled Check if your SSO supports non-password authentication mechanisms (e.g. MFA, X509, PasswordLessPhoneSignin).
  4. Click Save to save this setting.
