You can check the difference between the Password reset and password change here: https://www.axcrypt.net/blog/password-reset-axcrypt/ .
Please note: Password reset and password change are not same .
Password reset is not a way to recover encrypted files! It’s only to allow you to sign in to the AxCrypt app and web. The new password will be used to encrypt new files.
When you change (not reset) your password for your AxCrypt ID account, *all* files previously encrypted with that AxCrypt ID account will automatically open with the new changed password.
Please note: If reset your AxCrypt account password after key sharing a file with you then you will not get access to the key shared encrypted files with the new password(which was created after password reset). You have to use the old password to decrypt the encrypted files.
