I changed my laptop and installed version 2. I still have my older password and was able to sign in okay. My only challenge is each time I try to open a previously saved file, I get the message in the attached screenshot.
If I remember correctly, the previous version allowed saving each file with a unique password. This version does not ask me to enter that password.
In version 2 you can still open version 1 files but you’ll be prompted to enter the original [version 1] password. AxCrypt 2 will then decrypt and re-encrypt it in version 2 format once you’ve finished working with it.
If this doesn’t answer your question please reattach the screenshot.
