Open Profile → Account Settings → Sign-in methods.
Link or unlink an account
Tap Link beside Apple (on iPhone), Google or Facebook to sign in with it as well. Unlink stops it signing you in. You always keep at least one way to sign in, so your only one can't be unlinked: it says your only way to sign in.
Change your password
Tap Change beside Password, enter your current password and a new one twice. You stay signed in on this phone, and Byker signs you out everywhere else.
Set a password
Signed up with Google or Facebook? Tap Set beside Password to sign in with your email and a password too. Then you can unlink the others if you like.
Change your email
In Account Settings, tap your email. Byker sends a 6-digit code to the new address, and your email changes once you enter it.
