I think, you might clicked the Reset button in the sign in password dialog. That button is used to reset the AxCrypt account data in the locally installed AxCrypt app. That means, it will clear all the local contents cache of the AxCrypt app and restart the app like a freshly installed one.
Then you have to provide your account email address and password again to sign in to the AxCrypt app.
It is not an issue, the AxCrypt app Working like that only. Don’t worry about it.
still, if you are facing any issue please contact our support email@example.com.
