Firebase authentication email customisation

Question

I'm using firebase auth in my app and i'm setting up password-less email sign up.

I have managed to set the email from my own domain but how do i change the text sent in the email for magic link? I can see the configuration for the other template emails but not this one.

The email in question is this one:

Hello,  We received a request to sign in to teamname using this email address. If you want to sign in with your youremail account, click this link: link  If you did not request this link, you can safely ignore this email.  Thanks,

There is no way to edit the email template. The reason for this is that this allows bad actors to use Firebase to spam people, which would put the service at risk.

To control what message gets sent, you'll have to send it yourself and handle the verification flow with a custom email action handler. See How to modify Email Confirmation message - Firebase.

You could also take full control of the verification flow, and then use the Admin SDK to set the emailVerified flag of the user's profile.
