# What is members wallet?

Mixin Messenger serves as a member wallet to independently store another key in the Safe 2/3 multi-signature, as well as for logging into the Mixin Safe Dashboard, which requires you to download and install it together with your family members, friends, or coworkers, and log in with your phone number.

Mixin Messenger is available on iOS and Android devices. It can be downloaded from [App Store](https://itunes.apple.com/us/app/id1322324266) or [Google Play Store](https://play.google.com/store/apps/details?id=one.mixin.messenger). For more information, please read

The members wallet can be used to create and approve transactions, and each transaction needs to be confirmed by scanning the  QR code and entering the PIN via Mixin Messenger, so please keep your PIN safe and set up an emergency contact to protect your right to manage the members wallet.
