Reg: We use Entra to manage your application user login

We noticed that our account suddenly had a billing spike, and we identified that Entra External ID seems to be causing the issue. However, we are unable to find the specific reason for these charges. We checked with the Azure billing team, but they mentioned that they have limited access and advised us to raise a technical support ticket to get this resolved.

Hello ardhas ilearn,

Charges related to Microsoft Entra External ID are typically based on Monthly Active Users (MAU) for external identities (such as guest users, B2C users, or users authenticating through External ID flows). A billing spike can occur if there is a sudden increase in the number of external users authenticating during the billing period.
