Question about recovery account being the same as the account? on the authenticator app

Question

Hey there! I am planning to get a new iPhone in a year or two. But I was wondering if i should be concern about my recovery account being the same as my personal account. For context I only got one account and its a personal account, I don't have anymore mircosoft accounts. so it linked it as my recovery account back up. I do got 2 non mircosoft backup emails/phone numbers and the account recovery code saved and updated. But I am just wondering if there is a way to change my Mircosoft account back up recovery? I do have a trusted computer that I can access the account on using a security key. the account is a outlook/hotmail btw. So i was wondering if i need to change anything. or if i be good following the recovery steps from the Icloud? (I do have it backed up to the cloud ). I tried googling this question but it doesn't really bring up results. But i am sure I'm not the only one to have this problem. So please let me know if there is anything I need to know before switching Iphones.
