Looking for a small, dedicated device to perform the same function as an authenticator token app. Ideally, open source with the ability to select and display tokens without connecting to anything.
Think traditional RSA hardware token, only with the ability to add other tokens and flip through them.
(I don't see a related tag for anything like this, feel free to edit)
The Molto-1 by Token2 is a programmable, multi profile hardware token. I own one of those for a few months now and use it on a daily basis.
The Molto-2 supports 10 different profiles, 6 or 8 digit codes and SHA-1 and SHA-256 hash algorithms. Google Authenticator uses 6 digit codes with SHA-1, so the Molto-1 is fully compatible.
Programming happens with an Android app over NFC, so be sure to use a smartphone you trust. Alternatively the Molto-1i supports iOS. RTC resynchronisation also happens with the app. The app itself has pretty rough edges, but you can figure out how to use it.
One downside is the non-replaceable battery. It is supposed to last 4-5 years, and it has a battery indicator warning you early enough when it's running low.
I just realized they have a new multi-profile hardware token, the Molto-2. It is USB-programmable and features a bigger display for presenting QR codes, as well as USB HID emulation for automatic entry of TOTP codes on a computer.
