"After I switched accounts, Swimmo app will no longer connect with the watch. Instead, it shows "Authorization key incorrect" error message."


This error message occurs once you shared your Swimmo with someone else or simply you set up a new account without resetting the watch first. This error does not indicate any fault with the watch.

Why is this happening

For convenience, Swimmo app syncs workouts in the background (and wipes it our after syncing). What's more, by using the mobile app, you are able to modify your personal settings on the watch such as your swimming goals and pool settings.

That's why the connection with Swimmo watch must be safe and protected because there might be several people nearby with Swimmo app (e.g. families with multiple Swimmo watches, masters swimming group). 

For that reason, once you set up your account and connect Swimmo for the first time, your watch is given an authorization key of your account. 

What to do next
  • If you have access to the old account, log in under your old account, connect with your watch, and then go to Swimmo app -> Settings -> Troubleshooting -> Reset the watch. It will clear the auth key in the watch. Then without connecting again, sign out of your account and log in under the new account. 
  • If you don't have access to the old account, you will need to reset your watch to factory settings.
