In My account – one place for your email, password and sign-in, for every tree you belong to. Change it once and it changes everywhere. Remember, your email is what you sign in with, so use the new one next time.
Where to find it
Press your name in "Signed in as" (top row) → your card opens → Personal settings on the card's button row → My Details → My account (email, password, sign-in and Delete my account live there)
On a phone: if the card's buttons are tucked away, press ☰ Menu first.
