How to renew Azure B2C Sign-in URL SSL certificate?

Question

We've configured Azure B2C SAML application that works fine. By looking into the B2C Sign-in URL HTTPS SSL certificate validity it shows valid from 15/02/2022 to 15/02/2023. We are sure that we've not taken any additional steps to configure this SSL certificate. URL ex: https://xyz.b2clogin.com/xyz.onmicrosoft.com/B2C_1A_signup_signin/generic/login?EntityId=abc.com

Questions:

1. Is this SSL certificate managed by Azure?
2. Do we need to take any steps when it closes to the expiry date?

Pls Note: We're using an office 365 free-tier tenant, not using any premium P1 and P2 licenses.
I could not find any MS documentation on how this SSL certificate is being applied whether it's EV OR wildcard certificate. Could you pls share any such documentation link? Thanks.

Hi @Karikalan Ramakrishn • Please find my comments inline.

1. Is this SSL certificate managed by Azure?
Yes, this certificate is managed by Azure.

2. Do we need to take any steps when it closes to the expiry date?
No, you are not required to take any actions as this certificate is managed by Microsoft. If you check the Subject Alternative Name field of the certificate, you can see the FQDN of a lot of Azure Services, which means there are a lot of services that use this certificate and not just B2C. This is why it is maintained by Microsoft.

There is no documentation available specifically for the Azure SSL certificate., but as the SSL certificate is part of managed services, these are managed by Microsoft.
