What is the Authenticity Seal?
The Authenticity Seal is a security feature that helps you verify you’re on the genuine Microsoft login page. Think of it as a unique “watermark” that appears on official Microsoft login pages. Each organization has its own unique seal. The symbol changes every month.
How to Use the Authenticity Seal
- Before entering your login credentials, always check for the Authenticity Seal in the top right corner
- When in doubt, compare it with the current seal shown in your Teams or Outlook app
- Only proceed with login if the seals match exactly
