If you back up your Connected Accounts in the Salesforce Authenticator mobile app, you can restore them on another mobile device.
The back up and restore feature is available if you have a Salesforce account connected to the app. To use the feature and avoid disruptions, ensure you have at least one Salesforce account connected.
Before you restore your accounts, keep these things in mind.
- If the new device has a different phone number, change the verified number in the previous device before you restore your accounts. In your Salesforce Authenticator app on the previous device, tap the Settings icon (
) in the upper left corner, then tap Verified number. Complete the steps to verify your new number. You're not required to create a new four-digit passcode. You can now restore your accounts on the new device. - Connected Accounts are active on only one device at a time. If you restore your Connected Accounts on a new device, you can no longer access them from the previous device.
- To restore your Connected Accounts on a new device, restore your accounts before creating new Connected Accounts on the new device. You can’t restore Connected Accounts from a backup after creating new Connected Accounts.
- Custom connection names, custom usernames, and the sort order of your connections aren’t preserved. These settings return to their initial values. You can rename and resort your connections after you restore them.
- From the Let’s Get Started screen, tap Restore from Backup.
- When prompted, enter your mobile number and tap Send.
