If I lose my phone I have no totp access or sms access
I walk to the local phone shop and get a replacement sim for my number with a few of bits of ID and I regain sms access. Totp access is gone forever.
It’s clearly not worse that totp in every way.
I suggest exporting your password manager && your topt keychain onto an encrypted flash drive. I went through the horrors of having a phone die on me after migrating my topt to a local solution. Having a valid login cookie on bitwarden on my laptop was the only thing that saved me.
And that post is why sms is superior.
You vans I may be able to manage a backup and understand how these codes are generated. The average person does not.
From memory most totp apps don’t even migrate when you move from one phone to another - at least on iPhone. I haven’t done that for 5 years but I seem to remember having to create new entries.
