There are free alternatives. I've used Strongbox and it was pretty much pain-free once it was set up.

How does Google Authenticator work?
It's really easy to integrate into websites as well. I did so a few years ago. The TOTP algorithm is just a few lines of code. I adapted this implementation https://github.com/j256/two-factor-auth at the time. There are similar libraries available for lots of languages.
You need a library like that and a way to convert an otp:// url into a QR code, for which there are many libaries as well. The rest is just implementing a sane UX around this. Storing the user's TOTP secret server side is a bit tricky. I suspect a plain text field in a database is quite common for this; which of course would be disastrous if that database were ever stolen. Secret stores don't scale for this as they tend to be designed for just a handful of secrets. We ended up encrypting these totp secrets using a key from our secret store.
