Strap keeps who you are separate from how you slept: signing in gets you a profile and a handle, linking WHOOP gets you data. You can be invited by family before ever putting on a strap.
Strap Bot sends you a six-digit code. No password to forget, and the same chat later carries anything worth telling you about.
A verified email address, and an account nobody else can open.
Not open yet. It is coming, and it is meant to sit alongside Telegram rather than replace it — one proves an address, the other proves someone we can reach.
