How to verify without a phone?

I can't see an option that says verify via email

Hello Rim,

We understand that you're attempting to check the reputation on the account but come across the number verification option with no other way to verify.

Unfortunately, this will be the only option to be able to verify the account, but it is recommended to attempt visiting the
Enforcement Reputation website to view this information.

Try the suggested and let us know if this was helpful.

Best wishes!

Account security is no joke for the xbox live service this is why there has never been a serious breach of a major number in account data like somewhere else

If you can't follow the steps indicated contact xbox support for account security issues: (800) 469-9269 if you're in the US/Canada or

You will want to sign into her account at account.live.com

once there you can go to security in the blue bar at the top of the screen.

It will probably ask you to verify the account with a security code now if you do not have access to any of the security proofs (where MS is sending the code) then you can change the security proof BUT there would be a 30 day waiting period before the security
proof change takes affect.

You would still be able to sign into the account but anything that would require a security proof (changing password, phone numbers, security proofs) Once the 30 day hold is over at that point you would be able to do any of those things on the account because
the security proof would be changed at that point.

If you do have the capability of accessing the current security proof and can verify the account ownership with that then on the next page you would be able to change the current security proof you can have multiple security proofs (email addresses, Phone
numbers) so that if you do lose access to one you always have a back up.

Exactly this. You can do this from any browser on your PC, tablet, or phone as well as in the Edge browser on the console.
