So what is Passwordless Authentication and why should you use it?

Passwordless Authentication removes the need for you to enter a password and respond to a second-factor prompt each time you need to log into a Microsoft 365 app. Instead, Microsoft’s implementation of Passwordless Auth prompts you to match one of three numbers using the Microsoft Authenticator app at the exact time you need to login, this combines entering in your password the multifactor authentication prompt into a simple process.

The prerequisite for Passwordless Auth is your organisation has enabled the feature and you have the Microsoft Authenticator App setup for 2FA on your Phone with your work’s Microsoft account setup. If you don’t have that setup you can head to our Guide Register for 2FA – Microsoft Authenticator – RODIN to get that sorted first and reach out to Rodin support if you need Passwordless Auth enabled for your organisation.
