I developed Authorizer to have a cross-platform solution without any server/cloud-service. It is an offline hardware password manager based on PasswdSafe for Android. The concept is to use an old Android phone as your password manager. It can type the password over USB and Bluetooth on your target device. Supports OTP. Smartcard and WebAuthn support are on the roadmap. Doing also a lot of modernization on the next weeks. https://github.com/tejado/Authorizer
In Ask HN: How do you manage your passwords in 2023?
I’m happy to collaborate on Authorizer - a hardware password manager based on old Android phones. Next milestone: smartcard integration over USB. I would like to build a lib to abstract USB Gadgets on Linux. This is necessary for adding smartcard support (e.g., to store your GPG keys in Authorizer). I already did a lot of research about it, but more on an amateur level as I’m not a kernel dev. One further milestone on Authorizer is finding a next device (cheap, not too old Android, smaller, …) to base the development on. Project: https://github.com/tejado/Authorizer
In Ask HN: Who wants to collaborate? (April 2022)
I would trust them but I don't take the risk of "trust". There could be always issues which are out of your or the Password Managers control, e.g. crypto issues and also long term issues like quantum computing. Due to this, I keep all of my passwords offline, as far as possible. For mobility and comfort reasons, I developed Authorizer (https://github.com/tejado/Authorizer): "A Password Manager for Android with Auto-Type over USB and Bluetooth, OTP and much more. The idea behind Authorizer is, to use old smartphones as a hardware password manager only. To avoid manual typing of long and complex passwords everytime you need them, Authorizer provides Auto-Type features over USB and Bluetooth. It pretends to be a keyboard (e.g. over an USB On-The-Go adapter) and with a button press inside the app, it will automatically type the password for y

ou on your pc, laptop, tablet or other smartphone."
In Ask HN: How comfortable do you feel using cloud-based password managers?
https://github.com/tejado/Authorizer Please note, I'm the owner of this project. "The idea behind Authorizer is, to use old smartphones as a hardware password manager only. To avoid manual typing of long and complex passwords everytime you need them, Authorizer pretends to be an USB keyboard (e.g. over an USB On-The-Go adapter). With a button press inside the App, it will automatically enters the password for you on your pc, laptop, tablet or main smartphone."
In Password Managers: Under the Hood of Secrets Management
As I want to protect all my passwords offline at one place but have them also available mobile, I developed Authorizer. It is an Android password manager based on PasswdSafe with USB HID keyboard support to enter paaawords automatically on any device. Also stores TOTP/HOTP. The idea is, to have a complete offline device (hardend android without network stack/always flight mode on, baseband overwritten, ...). https://github.com/tejado/Authorizer
