how do I change my default authenticator on i phone 16

Hi,

Thank you for sharing your question. I understand how confusing it can be when you have both Microsoft Authenticator and Google Authenticator on your iPhone and want to choose which one should work as your default authentication method.

On iPhone, iOS does not allow you to set a “default authenticator app” at the system level. Instead, the service you are signing into (Microsoft, Google, Facebook, etc.) decides which authenticator to use. This means you must set your preferred authenticator within each account’s own security settings.

Here’s how you can make sure the authenticator you prefer becomes the one used by your accounts:

How to Choose Your Default Authenticator (Per Account)

For your Microsoft account

Microsoft lets you choose Microsoft Authenticator as your primary verification method.

Go to: https://account.microsoft.com/security

Select Advanced security options

Under Two-step verification or Additional security, locate Authenticator apps

Choose Microsoft Authenticator as your default method

Remove or disable Google Authenticator if you no longer want it used

I hope this helps.

Best Regards,

Noel
