Hello Dang,
AxCrypt will allow the users to decrypt the encrypted file with the original password which is used for encryption.
If the file was encrypted with a different password than your sign in password, then you have to enter the file password while viewing/decrypting the encrypted file.
For example: Try to encrypt a file with your AxCrypt password and then reset your AxCrypt account password using Reset Password Feature. Now if you open the encrypted file, you will be prompted for enter the file password (which is used for encryption of the file).
If you think you almost know the password, we have simple software allowing you to try to find your password, and you can download the most recent version from https://account.axcrypt.net/Download/AxBruteForce.exe and read of how to use it at https://forum.axcrypt.net/axcrypt-brute-force/ . Please note that we cannot provide support beyond this.
If the above does not help,please provide more information about the issue and write a mail to support@axcrypt.net .
