SMS is no longer recommended as a means of 2FA, as it's very vulnerable. Some sites still rely on it, unfortunately. However, it appears Reddit does support TOTP.
Somehow this reminds me of a wise saying: "Every problem in CS can be solved by adding level of indirection. Except for the problem of excessive number of indirections".
