Firebase now supports phone number
authentication in addition to logging in
with email and password or identity
providers like Facebook and Google a
phone number is validated using a
one-time SMS message and Firebase
provides all of the infrastructure to
handle this I'm Lawrence and in
this firecast I'll show you how this
works typically when using Firebase off
you'll provide a number of signin
methods such as signing up or signing in
with Google Facebook or email well now
there's a new option as you can see here
sign in with phone to be able to do this
you'll first need to enter your phone
number which you can do from a standard
dialogue when doing it from the web
you'll also be able to validate this
with a
recapture once you have a valid phone
number you can verify it Firebase will
send an SMS to your device containing a
code you simply enter this code and it
will be verified with Firebase if it's a
correct code you'll be good to go
otherwise you'll have to re-enter or
resend once a user is signed up with
phone off you'll also see them in the
Firebase console it's a pretty simple
lightweight process it's also easy to
build it using the open source Firebase
UI libraries there's a link to them in
the description below also check out the
Firebase developer site for more
information on building for Firebase off
and don't forget to subscribe to the
Firebase Channel on YouTube for more
videos including more on how to use
phone on off on iOS Android and the web
I'll see you
