Can’t Create or Update Your Mysa App Account

Last updated: September 9, 2026

Use this guide when you cannot create a Mysa app account, do not receive the verification or password-reset email, or cannot update your name or password.

Make sure you are using the right account

Your Mysa app account controls thermostats in the Mysa app. It is separate from the store account used for purchases, orders, invoices, and shipping.

Account creation fails

  • Update the Mysa app from the App Store or Google Play.

  • Check that the email address is typed correctly.

  • Choose a new password and submit the form again.

  • Check Inbox, Spam, and Junk for the verification email.

  • If that email is already registered, return to the sign-in screen and use Forgot password? instead of creating another account.

Password-reset email does not arrive

  • Enter the same email address used in the Mysa app.

  • Check Spam and Junk and wait a few minutes.

  • Request one new reset email, then use the newest link.

Profile changes do not save

Try the change again while connected to the internet. You can update your name in Menu → Account → Profile. The email address on an existing Mysa app account cannot be changed; a different email requires a new account and re-pairing the thermostats.

Still not working?

Email support@getmysa.com with the email address used, phone type, app version, and the exact error message. Do not send your password.
