Como puedo solucionar esto me deja ingresar para matricularme en linia

The error message you are encountering, AADSTS75011, indicates that there is a mismatch between the authentication method you used and the one that the application is requesting. Specifically, you authenticated using 'MultiFactor, PasswordlessPhoneSignIn', but the application is expecting 'Password, ProtectedTransport'.

To resolve this issue, you can try the following steps:

1. Contact the Application Owner: Since the message suggests contacting the UPN - Identity Banner WSO2 application owner, this is a good first step. They may need to adjust the authentication settings for the application.
2. Check Authentication Methods: Ensure that you are using the correct authentication method as required by the application. If possible, switch to the method that the application is expecting.
3. Request Fresh Authentication: If you have control over the SAML request, you can try to request a fresh authentication by including forceAuthn="true" in the SAML request. This may help align the authentication context with what the application expects.

If these steps do not resolve the issue, further investigation may be needed by your IT support or the application owner to ensure that the authentication methods are configured correctly.
