Hi @Fernando Benavides Navarro
Kindly note that since this is a public forum, in order to protect your privacy, I have replaced your domain name with example.com. Thanks for your understanding and do not forget to hide your personal information in your post.
According to your description, I have the following questions to confirm with you:
- Does your phone number work? If your device is powered on and you still aren't receiving incoming calls or text messages, there may be an issue with your network.
- Have you set up a block for receiving unknown numbers?
Based on your screenshot, you set other security verification options, and you choose other options to try again to check if the problem persists. Also, if you have an Azure AD MFA or Azure Active Directory Premium subscription.
- Go to the Azure portal, and then open Azure Active Directory.
- If you want to change the default active directory, click Manage tenants, choose the active directory, and then click Switch.
- Choose Users, open the profile of the user that has the problem.
- Check whether the Block sign in is enabled. If yes, disable the option.
