Signing in without a password
Straby has no passwords. You enter your email address, you receive a link, you are in.
A sign-in code lasts thirty minutes. After that, ask for a new one from the sign-in page. It arrives at once.
A team invitation lasts seven days. It travels by WhatsApp and gets opened the next day, hence the longer life.
The email does not arrive. In order of likelihood: it is in spam; the address has a typo; the link was requested more than thirty minutes ago. Ask for a new link before trying anything else.
Signing in on a new phone works the same way. Nothing is tied to a device: your cards and contacts belong to your email address.
Why no passwords. A password is one more thing to lose, and the reset email is the same email you would receive anyway.
