YOU NEED TO DO THE FOLLOWING:
Register for the LoginTap account, you will receive needed tokens & files
Include our backend library and add 2 DB tabes
Add the JS widget to the frontend of your web app
Use Tech Docs
for more on endpoints between LoginTap and your site
ALSO CONSIDER YOUR INTERNAL PROCEDURES:
When to call on LoginTap - we highly recommend doing it when user is recognised by cookies etc; BUT you can choose to use it as a pure 2FA, after your login is passed.
Calling on LoginTap right on entry, or on user's actions, for example, for an order confirmation, depending on your use case.
Checking if existing session timeouts keep making sense or could be shortened
