Android-Level Security Hardening - AudioCodes C470HD User's And Administrator's Manual

CHAPTER 1 Overview
Use the sign-in mode Sign-in with other device option. In this mode, users do not type the
■
password on the device but instead obtain a code on their PC / laptop to be used to sign-in;
the phone obtains a private token that enables it to access Teams cloud; this token, unlike
a password, allows only that device which obtained it to reuse it. The token is stored on the
secured file system.
Leverage Multi-Factor-authentication (MFA) to improve sign-in security.
■
■ Reduce the expiration time of the sign-in for devices which are connected remotely
(outside the organization's network) versus devices inside the organization's premises.
