Hello Spasé,
We have literally hundreds of thousands of users a succeed in signing in, both using the app and the web.
I think you perhaps are not careful enough when you type the password – or you are not aware that upper and lower case characters are different, and spaces and accents are significant when typing the password.
I suggest you use the ‘show password’ option in both the web and the app, and ensure that what is type is truly identical.
AxCrypt will allow the users to decrypt the encrypted file with the original password which is used for encryption.
AxCrypt will use the AxCrypt account password to encrypt/decrypt the files. The account password is used/involved to encrypt the files with the AxCrypt app.
Still, you can open/decrypt the old encrypted files with the original file password(which was used in the file encryption process).
So please try to remember the file password(which was used in the encryption process) to decrypt/open the old encrypted files.
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.
Still, you are facing any issues, please provide more information about the issue and write a mail to support@axcrypt.net.
