Does Supertokens do any phone number normalisation? It appears not. I made an account with [country code]0[rest of number], and when I logged in with the same number but without the zero, it created a new account 🤔

We use phonenumberlib to do the normalisation part. And that lib follows the international standard for phone number format

But feel free to open an issue about this and we can have a look

Does it do it for `updatePasswordlessUser`?

I'm now just setting the phone number on the user directly

If not I can normalize it before, no problem 😄

Ah right. No. It doesn’t. It does it only in the API call when a user signs in or signs up.

You will have to normalise the phone number yourself before giving it to that function
