Lightweight password manager for Android, KeePassDX allows editing encrypted data in a single file in KeePass format and fill in the forms in a secure way.
I'd recommend BitWarden if you want a cloud based solution, or KeePassDX if you want a local database that you can then backup and sync independently. Both are open source and at least KeePassDX allows you to auto-fill passwords both in the browser and in your apps.
Is there a way to KeePassDX autofill in browsers?
