I've been using Enpass for a while now and I really like it. I bought premium for both Windows and Android. However, I'm kind of concerned about the security. I know there was a third-party audit, but in the meantime there could have been new vulnerabilities that we don't know about. Open-sourcing Enpass would make it much more secure. Besides, contributions from the community could improve the app even further.
And there's no need to worry about income, there will still be plenty of people who will pay for the premium version because it's much easier than compiling the app from source for every update. And the people who would rather compile from source than pay for it probably weren't going to be paying for the premium version either way (and just pirate it instead or something).
I know that this is not an easy decision to make, but I would really appreciate it if you guys would seriously consider open-sourcing Enpass. I think it would be better for everyone. Thank you.
