My password works on both my iphone and iPad but not long works for my Mac desk.  This seems to have occurred with the latest update.

Hi @onecat

Welcome to the Enpass Forums.

Regarding the master password not working, for quick troubleshooting, please try the below steps - 

1. I recommend checking this highly useful troubleshooting guide.
2. Ensure that you are synchronizing with the correct cloud account. The cloud account from which you are trying to restore your data should be the same as the one you are using to synchronize your data on other devices.

You can also refer to the following Forum as the same is being discussed there -

If the above instructions do not help, kindly share the below details with me and I’ll get this investigated for you -

1. The version of the Enpass app and OS you are using on all your devices.
2. Is the master password working on your other devices or are you accessing the Enpass app through biometrics/Face ID?
3. The number of vaults you have in your Enpass app on your other devices.
