# Profile and Account Security

> Update your profile, change your PIN, sign out, and understand account deletion.

## Profile

Open **Profile** to review personal, contact, school-role, academic, teaching, and account information available to your account. Update editable details and save before leaving.

Some identity and school-assignment fields are read-only because an authorized school operator manages them.

## Change your PIN

Use the account password or PIN change action, enter the requested current and new values, and keep the new credential private. Do not reuse another person's access PIN.

## Sign out

Use **Sign out** when leaving a shared device. Closing the browser tab is not a dependable substitute for ending the signed-in session.

## Account deletion

Account deletion can affect access to school records and connected product modules. Read the confirmation and contact the school if records must be transferred, archived, or retained before deletion.

<Warning>
  Never share sign-in credentials, access PINs, password-reset links, or one-time payment information in Kralis AI, broadcasts, chat, or Classroom.
