Currently support only macOS.
This package use build-in macOS security util to manage secrets in keychain storage.
Homebrew:
brew tap alekseevav/tap
brew install f2f
Brew formula named f2f because of ruby name convention.
From sources:
go get github.com/AlekseevAV/2f
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.
You can specify keychain name by setting KEYCHAIN_NAME environment variable.
All available commands:
2f -add [-7] [-8] name
2f -delete name
2f -list
2f -help
2f name
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.
