How to have spare set of keys when it comes to Microsoft Authenticator? iOS APP automatically sync devices

Sunny PA Wong 1 Reputation point

I need help with having spare set of keys when it comes to Authenticator. I have another device but how to install redundant existing MS Authenticator database to my secondary iOS device which has same account profile except Apple ID and phone number?

iOS APP sync between devices; adding 2FA here automatically updates others; redundancy reduces manually immediately backup this device & restoring In others.

It is for myself but I am willing to use Family Share if there is no other option.

    Hi @Sunny PA Wong

    welcome to Q&A

    if i understood correctly, You need to setup authenticator on 2 different IOS/Android device and same should active on both the devices.

    Option 1- You can simple Backup Autnetcator app on Icloud and same you can restore to another IOS device. (Not sure about ANdriod)

    Option 2 -

    Manually Add Accounts

    Log in to Each Account:

    Go to the security settings of each account you use with Microsoft Authenticator.

    Add to Secondary Device:

    Choose the option to set up a new authenticator app.

    Scan the QR code with Microsoft Authenticator on your secondary phone.

    This will add your account to the new phone.

    Repeat for All Accounts:

    Do this for each account you have in the Authenticator app.

    Please accept as answer if it helps
