Currently support only macOS.

This package use build-in macOS security util to manage secrets in keychain storage.

Install

go get github.com/AlekseevAV/2f

Usage

New keychain storage will be created on first run:

go run main.go -add gmail
password for new keychain: xxxxxxx
2f key for gmail: afafasdfdsfa

After that you can find new keychain in "Keychain Access.app" and get full access with your password.

All available commands:

2f -add [-7] [-8] name
2f -delete name
2f -list
2f name

Example

Add key:

$ 2f -add gmail
2f key for gmail: asdfasfrwerwr

Get two-factor key:

$ 2f gmail
516214

Delete key:

$ 2f -delete gmail

By default all keys created with 6 digits code, but you can set 7 or 8 digits by:

$ 2f -add -7 gmail
2f key for gmail: asdfasfrwerwr
$ 2f gmail
1524561

$ 2f -add -8 gmail
2f key for gmail: asdfasfrwerwr
$ 2f gmail
51635261

Inspired by this project - https://github.com/rsc/2fa.

But storing keys in files with base32 encoding just not enough secure for me.
