Teacher App sign-in and replacing a phone
A successful Teacher App password or QR sign-in starts the current session and signs out the previous session automatically. You can sign in again on the same phone, after reinstalling, or on a replacement phone without logging out of an unavailable phone first. Only the latest successful sign-in remains valid. An old or expired session must sign in again. A successful QR is single-use; get a fresh QR if it was already used or has expired.
School administrators can still revoke a lost phone without signing in elsewhere: open HRM → Manage Employees → Update → Teacher App Credentials → Teacher App device → Release device, review the teacher and phone, then confirm. Existing Employee Update or Teacher App Device privilege must cover that campus. Release invalidates the session and clears its notification registration and attendance permission. A stale confirmation cannot release a newer login; refresh device details and review again.
Login registration is separate from attendance-device approval. Signing in does not grant an extra attendance permission or change credentials, classes, subjects, app access or school-owner approval requirements. No message is sent by sign-in or release.
Open Edit Employee
Open Manage Employees and use the existing edit action on the employee you want to change. Existing access permissions remain unchanged.
Choose your layout
Classic opens first unless you save another default. Use Try the new layout or View old layout to switch. A layout in the page address takes priority for that visit. If saving a default fails, your previous choice remains; try saving again. Switching keeps the same page and its current choices.
Keep the original controls
The same employee fields, photo controls and save controls remain. Switching layouts does not save changes or upload a photo. Existing loading and error behavior remains.
