Setting and changing a child's PIN

For parents· 2 min read

A child's 4-digit PIN is their sign-in credential. Set it when you add them, reset it whenever you need.

A child's PIN is their sign-in credential. It's a 4-digit code, stored as a cryptographic hash (we can't see the actual digits), tied to that one child profile.

Setting at add-time

When you add a child, the wizard's last step is Set PIN. You enter 4 digits twice; the second is for confirmation. The child can sign in the moment you save.

Changing later

Family → tap the child's row.
Reset PIN.
Enter the new 4-digit PIN. Confirm.
Save.

The old PIN stops working immediately, and the child is signed out everywhere: they sign back in with the new PIN.

What makes a good PIN

Memorable to the child — they'll type it daily.
Different from each sibling — so they can't sign in as each other.
Not their birthday or street number — siblings can guess those.
Not "1234" or "0000" — Keybaki does not block them, so it is on you to steer clear of the obvious patterns.

Sharing the PIN

Write it on a piece of paper they keep at home, not on the device.
Or just remind them verbally — kids memorise 4 digits in one repetition.
Never put the PIN in WhatsApp, SMS, or anywhere shareable.

If the child forgets

There's no recovery flow — you just reset it. Two taps from Family.

Common issues

Child types the right PIN but can't sign in. Check the first name they typed. There is no list to pick from: the child types their first name exactly as you saved it (capital letters do not matter) and Keybaki checks the name and PIN together.
Two children share a first name. Keybaki refuses a second learner with the same first name, because sign-in is by first name under your number. Give one of them a middle name or nickname from Family.
PIN won't accept letters. Digits only, exactly 4. The keypad on touch devices is numeric to keep it simple.
