Questions? We've Got Answers

We query your Entra ID daily via MS Graph to check each secret’s expiry date. If any are within a risk window, we email your team to renew well before expiry— no more blind guesswork or last-minute panic.

We only need read-only permissions (Application.Read.All) to fetch expiry metadata.
Your actual secret values stay private—RenewB4 only sees expiration dates and metadata.
