# Signing in

Three ways in, one account, and no password to forget.

## Coming back

Whatever you used to sign up — **Google**, **Apple**, or an email address —
use it again and you land in the same account. You can add the other routes
later from your profile, and adding one does not take the others away.

A provider button is only drawn when it is fully configured, so a button you
can see is a button that works.

## Use the same email address

This is the one thing worth being careful about, because it is easy to trip
over and there is no warning at the time.

**An account is its email address.** Sign up by email and later press Continue
with Google on *the same address* and the two are joined automatically — one
account, one set of sites.

But sign in with an address the account has never seen, and you get a **new,
empty account** rather than a refusal. Three ways that happens without anybody
doing anything strange:

- **Apple's Hide My Email** gives us a relay address, which will not match the
  one you typed when you signed up.
- **Your Google account is on a different address** from the one you signed
  up with.
- **Gmail ignores dots in addresses and we do not**, so `a.lice@gmail.com` and
  `alice@gmail.com` are two accounts here and one inbox at Google.

If you sign in and your sites are missing, you are almost certainly in the
second account rather than looking at a site that has vanished. Sign out, sign
in the original way, and everything is where you left it.

## There is no password reset

Deliberately. Press **"Can't log in?"** and we email you a **one-time sign-in
link**: press it and you are in.

A reset flow makes you invent a new password at the worst possible moment —
locked out, in a hurry — and that is how people end up with a password they
cannot remember next time either. A link that signs you in solves the actual
problem, which is getting back to your site.

The link is single-use. Asking for another invalidates the one before it.

## Setting a password

You do not need one. If you want one, set it from your **profile** once you are
signed in, and change it in the same place.

That is the only place a password is ever set. There is no screen that asks you
to choose one while you are locked out, because that screen is the reset flow
this product does not have.

## Confirming your address

**No session starts until the address on the account is confirmed.** Sign in
with Google or Apple and that has already happened. Sign up by email and the
confirmation is in your inbox.

It is not optional and it is not a formality: an account that can be made
without a real address is one a script can make ten thousand of, and there are
free credits attached to each one. See
