Services / Auth & licensing
Sign-in, two-step verification and license keys, done properly.
Authentication is where small mistakes become incidents. I build it the way I built the sign-in for my own admin: passkeys, two-step codes, lockouts and audit logs, all tested.
Good fit: Products that need accounts, paid access or license keys for their software.

Questions
Can you add passkeys to my existing site?
Usually, yes. Passkeys can sit next to passwords, so your users can switch at their own pace.
Is licensing ever unbreakable?
No licensing system is. The goal is to make it inconvenient to share keys and easy for you to see and revoke abuse.
