through your extension is great !!
but i prefer using this method
because sending bulk emails through firebase is quick you don’t need worry about verifying the otp or creation of it in your server. plus you don’t need a custom script. also i noticed you are using you gmail to send the otp email to users. the limit of sending email from gmail using any method be it smtp or using dashboard or api is 500 only. so even if one has 1000 users and growing this method is not sustainable. whereas firebase allows you to send unlimited otp emails in there free plan. plus its is safe and quick.
Please Don’t think that i am degrading your extension. it is just my opinion.
