Important information about your security:
The TOTP tokens you enter here are transmitted directly to your watch. They are not sent over the network, nor stored on your phone, nor backed up to Pebble's servers. However, I can not guarantee that they will remain forever safe from prying eyes.
If you unload the app from your watch:
As the tokens are stored only on your watch, unininstalling the watch app will delete them permanently.
Please do not make this app - or any other - the sole means of accessing your accounts.
