How do I regain access to my Microsoft account if I accidentally deleted my Authenticator app?

Question

I accidentally deleted my Authenticator app on my phone, and I failed to set up two-factor authenticator, so I cannot access my other Microsoft account. What measures do I have to take to regain access since I need it to use certain apps and software for college. Thank you so much.
