I'm trying to figure out if it's possible to use custom HTML in the Passwordless email OTPs sent through AWS Cognito. If it is possible, what are the steps to do this, especially if I have SES enabled and everything is in production?

You might want to start by checking out AWS's documentation on message customizations for user pools. Here’s a link to it: https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pool-settings-message-customizations.html. It should give you a good idea of what can be modified.
Currently, you can't customize the HTML in email OTPs. I contacted AWS support about this last month, and they confirmed it's not supported yet. Hopefully, they will add this feature in the future!

Ohh, thanks for the update. I guess I'll have to work with what's available for now.
