I want to send email verification code (not link) to user's create an account on my website with email.
Using firebase authentication, the method is send Email Verification.
Problem is firebase sends a verification link to user's email. Is it possible to send verification code of 6 number to user's email if yes then how it can be done?
Thanks.

I am working on a mobile app, where I already set up the following authentications in firebase:
phone number (OTP)
Google login
Facebook login
Question 1: For users logged in via OTP, I would like to request their email address, and ask them for verifying. I dont need password, because they will still log in with their mobile number, I just want them to verify their chosen email address. How can I do that in firebase? I know its possible to ask for verification with email/password login, but I dont need any passwords. Maybe I shall just add a dummy password in the background?
Question 2: Users logged in via facebook already have an email address that they use to log in. However I want them to verify their email address. As far as i know, email verification in firebase only possible with email/password authentication. How can I do an email verification with facebook authentication? Or lets say user can type in any email address (without password), and I send them a verification email. It is basically the same problem as in 'question 1'
Question 3: Users logged in via facebook / google authentication. How can I verify their phone numbers? I assume I can just simply do an OTP verification and link it to their existing authentication right?
Thank you,
By default firebase's sending a link to verify the user email, but I want to send a otp with that email. So is there a way to customize that email or send a otp and then once the user entered the correct code on the app get Firebase to mark that user account to email verified?
What you're describing is quite literally what the default Firebase flow does: it send an email with a link that includes a OTP to verify the email address.
You can do a certain amount of customization of the email action handler page that the emails link to. If that is not enough, you will have to implement your own flow, and can then use the Admin SDK in a secure environment to mark the user's email as verified.

Is it Possible? can I send email verification before I create a user with email and password in Firebase authentication using flutter?
I wanted to know this because if I register the entered mail and then if I send email verification, then if the email account is not valid(i.e the email format is correct, but it is not present in google database to send link to email), then it would simply create a record in Firebase authentication which is a loss of storage, so I would like to know.
Thank you
There are two providers for signing in with email to Firebase:
Through Email+password. There is no way to require the user to verify their email address before they can sign in with this provider. You can of course prevent users without a verified email address from using the app, and accessing the data.
Through Email link. Here the user gets an email with a sign-in link, so their email address is implicitly verified as part of signing in.
If you want to require the user to verify their email address before they can sign in, it might be best to have them sign in through an email link.
In addition to #Frank's answer, when a user signs up you can send verification email to them. You can always check if the user has verified their email in your app by checking the isEmailVerified property as well as in security rules.
Talking of database storage, you can run a scheduled cloud function every midnight to delete data of users who have not verified their email.
You can refer to this answer for a detailed explanation on periodically deleting unverified users.
I am creating an app where the user has to signup with an Email and Password. I want firebase to first verify the email if it does exist and it is an email and sends a link to the user to verify the email after this creates the account in firebase. So how can I do it can anyone tell me?
This has been covered quite a few times before, so I'll provide some links below. The bottom line is that the Firebase email+password provider provides no way to require email verification before account creation. The closest it has to that is the email link provider, which sends an email that signs the user into an account (without entering a password).

I've recently found out that, if Evernote's user does not verify his email address, all requests to Evernote API is not working. But I didn't find any ways to request email verification in Evernote's web interface, looks like the proposal to verify email appears randomly ? Are there any ways to request email verification from the user ?
You can ask users to change their email address via the page on the web, which will send them a verification email and verify their address.
