Hey I'm trying to link providerData with providerId = "password" using firebase admin SDK

environment :

• Firebase SDK version: 10.0.2
• Firebase Product: auth
• Node.js version: 16.13.0
• NPM version: 8.1.0

The problem I'm trying to link providerData using firebase admin SDK in order to link providerData with providerId = "password" . I'm using updateUser method and pass providerToLink object in order to link providerData. updateUser method will return this error :

• code : auth/invalid-provider-id
• message : The providerId must be a valid supported provider identifier string.

Relevant Code:

await admin
            .auth()
            .updateUser(user.uid, {
                providerToLink: {
                    uid: user.email,
                    email: user.email,
                    displayName: user.displayName,
                    providerId: 'password',
                },
            })
            .catch((error: any) => {
                console.error(`${error}`);
            });

If I understand correctly providerToLink is used when you want to link a user to a specific provider, such as google.com. If you want to set a password to a user you should be able to set it in the updateUser payload. I may have misunderstood your requirement here. Adding @prameshj for more context.

The list of valid provider ids can be found by invoking this API call - https://cloud.google.com/identity-platform/docs/reference/rest/v2/defaultSupportedIdps/list

In this case, is a password change being attempted?

Have you found the answer?

I don't think you can link a password provider directly. You could just call updateUser with the email you want (and the password when you know it).

That's odd because you can unlink a password provider.
