How to Register or Log In to Mixin Messenger with a Phone Number?

Mixin Messenger supports two ways to register or log in to your account — using a phone number or using a mnemonic phrase.

This guide explains how to register or log in with your phone number step by step.


1. Registration or Login Entry


  1. Open the Mixin Messenger app.
  2. On the home screen, tap Create Account or Existing Account.
  3. Choose the Phone option.



2. Enter Your Phone Number


  1. In the country code selector, choose the correct country or region (e.g. +86, +852, etc.).
  2. Enter your phone number.
  3. Tap Next to confirm.



3. Verify the Code


  1. Mixin will send a 4-digit SMS verification code to your phone number.
  2. Enter the 4-digit code in the Mixin Messenger app.
  3. Once verified, your registration or login will be completed successfully.



4. Initial Setup for New Accounts


If this is your first time registering for Mixin Messenger, follow these steps:


  • Set up your profile photo and nickname.
  • Create a PIN (wallet password) to protect your assets.
  • Once completed, you’ll be taken to the main Mixin Messenger interface.


5. Frequently Asked Questions (FAQ)


1. What should I do if I don’t receive the verification code?

Please refer to this guide: [What to do if you don’t receive the SMS verification code?]


2. What if I can’t tap “Next” after entering my phone number?

Please make sure you’ve selected the correct country code and entered a complete phone number.


3. I’ve changed my phone number — can I still log in to my old account?

It depends on your situation:


  • If you are still logged in:

You can change your phone number directly via Profile → Personal Info → Phone Number.

See: [How to Change Your Bound Phone Number?]

  • If you’re not logged in:

If you can’t log in with your old number, you can recover your account using a recovery contact or mnemonic phrase.

4. What should I do if I get a network error when logging in?

Try switching your network connection — between Wi-Fi, mobile data, or VPN — and try again.


5. Can I log in to the same account on multiple devices?

No.

Accounts logged in via phone number or mnemonic phrase can only be active on one mobile device at a time.

When you log in on a new device, the previous session will automatically be logged out.

However, mobile and desktop versions can stay online simultaneously since the desktop app uses QR code login authorized by your phone.
