I would like to have my users put in a code for any new device used for security. So if they logged in via PC they need a code (initial signup code is fine) but then if they also logged in via mobile, they would need a code for that device too

Hey @Kristian Lake, I briefly looked over the blog post u shared, it seems the setup is mainly made up of: • Cognito User Pool - can be created using sst.Auth • DynamoDB Table - can be created using sst.Table • Lambda Functions - can be created using sst.Function I’m not familiar with the architecture enough to share more on top of my head. But if you have specific questions, I will try to share more details w/ respect to that.

thanks Frank.
