Salesforce Authenticator is one of the most secure methods for Multi-Factor Authentication (MFA), helping protect user accounts and sensitive business data. Since a user can have only one Salesforce Authenticator app connected to their account at a time, replacing or losing a mobile device requires disconnecting the existing authentication before connecting a new device. If the Salesforce Authenticator app stops working or a user changes their phone, the easiest solution is to disconnect the current device and complete the setup process again. It’s also a recommended security practice to remove all verification methods from a user's account when they leave the organization, ensuring that no unauthorized access remains. In this blog, we’ll walk through the complete process of disconnecting Salesforce Authenticator and connecting a new device. Why Reset Salesforce MFA? Resetting Multi-Factor Authentication (MFA) helps maintain the security and integrity of your Salesforce organization.
