## Motivation

I've used authenticators that are packed with features. They allow you to save your secret keys, sync them across different devices through the internet, also import/export the keys by QRCode. If you are looking for tools like that, I recommend https://authenticator.cc , it's handy, open source and well documented 👍

However, password managers such as Bitwarden, Apple Keychain ... etc already did a very good job in storing and syncing keys across devices. I want to rely on them in secret key management, and let the authenticator extension do only one thing - generate TOTP for 2FA, nothing more.

This is where Mini Authenticator comes in. It designed with a "less is more" philosophy in mind. I cut all functionalities that already handled by password managers, and only perform the pure mathematical calculation of TOTP. So it doesn't require storage, read/write your web pages, internet access, special permissions... etc. And most importantly, it's open source, so everyone can inspect and help improving it in future.

I agree that this extension is not for everyone, but only those already using password mangers to manage their secret keys, also those who concern about chrome extension permissions and abilities.
