I can’t help with bypassing a phone password using Emergency Call or any other method.
Use the official account recovery option for the device.
Contact the phone manufacturer’s support.
Contact your carrier for account or device assistance.
If it is your phone, use the built-in erase/reset process and restore from backup.
Visit an authorized repair center with proof of ownership.
If you forgot a work-managed device passcode, contact your IT administrator.
If the phone is lost or stolen, use remote lock or erase tools from your account.
