You work from several devices, you change jobs, and sometimes you lose a phone. Plankwork has each person look after their own way in, so nothing about your sign-in depends on someone else being free to help.

Sign-in with a password, a login link, or your company’s Google or Microsoft account.
A password reset you can do yourself, by email.
Two-step sign-in, with recovery codes for a lost phone.
Settings that belong to you and follow you to every board.
A private record of what happened on your account.
Email controls, and closing your account when you leave.

The full chapter, with every step and setting, is in the app: open your account menu and select User manual.
