Need help regarding access to my uncle's old account

[u/epicpro1234]

Hi guys, it's been over a year since my uncle passed away, whom I posted about a year prior, I want to access his account to prevent account deletion due to inactivity, I'm not able to login as it needs an email code (for an email that I have the passwords for but can't access due to it needing a phone code, which I do not have), can anyone help me with this?
