Password manager for Android, Linux, and Windows

Question

I am looking for password manager with following features:

• has Linux, Windows and Android versions (different programs capable of using the same database are also OK)
• does not require additional manual saving after new password was added (it eliminates KeePass 2)
• it is possible to add it to autostart, without asking for password immediately after start (it eliminates KeePass 2)
• passwords are not leaving computer (no kind of any "cloud synchronization", also for encrypted passwords)
• password database is encrypted until user gives master password
• ability to export all data from program
• open source
• actively maintained software
• ability to generate random password

Strongly preferable:

• there was an independent security audit
• recommended by security experts
• gratis
• autotype available

Answer 1

Enpass is the closes thing I have found to your requirements. It fails your requirements on open-source only.

• Has Windows, Mac, Chromebook, Android, iOS versions, and Blackberry versions
• Autosaves / syncs
• Optional autostart, without asking for password immediately
• Passwords are stored locally, with optional sync to personal cloud storage accounts (i.e. Google Drive, Dropbox, Box)
• Database is encrypted with master password
• Passwords can be mass exported
• NOT Open source, but has community forum for suggestions, etc.
• Actively maintained
• Password generation (with recipe)
• Supports browser autofill

And a bonus, which is very important to me, it is user-friendly, and has a gorgeous interface. It can store anything from standard passwords and accounts, to hunting licenses and lens prescriptions.
