what (is this ๐ฉ)
Emojies as TOTP, because.
why
Because we all could use a little more emotion in our lives ๐ค Go show the world how you really feel!
It's a great companion for any app that uses 2FA - as every app should! Make your app's 2FA users as star-striking as your app! ๐คฉ
So whether your mascot is:

moths has got you covered! ๐ชฐ
P.S. These emojies wasn't chosen by accident (random), they really are the 10 utmost frequently used (animal) emojies of 2021

how
Running this is quite easy ๐จ
- Download the dependencies โฌ
Note
You can skip this step and let the run
-command handle it - but you knew that ๐ง
go mod download
- Make a secret of 32 characters ๐
echo -n "MOTHS_SECRET=" > .env
echo 'moths' | sha256sum | base64 | head -c 32 >> .env
- Run the program ๐
go run .
As I said, easy-peasy! ๐
options
To setup a new moth
-generator, you must call moths.NewMoths
as
gen, err := moths.NewMoths()
But I do recommend to add some customization, as it will fail immediately if not.
Like so
gen, err := moths.NewMoths(
moths.OptionWithSecret(secret), // 32 character secret
moths.OptionWithInterval(time.Second), // Each is only valid for a second
moths.OptionWithAmount(6), // Each must is always `6` emojies
moths.OptionWithEmojies(emojies.CATS), // A pure slice of cats
moths.OptionWithTime(time.Now().AddDate(10, 0, 0)), // 10 years into the future
)
There are a few options to choose from, these are
Warning
Options marked with an asterix (*) are required!
generating
Now that you have a sparkly new moth
-generator, you can use it as
otp, err := gen.Next()
Now that you have an OTP
, you can use its functions
validating
To validate, you'll need both the moth
(or the token
) and the generator
token := otp.String() // Ideally you'd get this from the user
ok := gen.Validate(token)
emojies
To use your own set of known emojies, you can reference the cat
-emojies.
I've chosen the cats
as it's a great reference, both for creating and re-using.
If we would like to add an easter-egg to a pure bred slice of cats, we could do it like:
// A slice of cat emojies and a single hotdog ๐ญ
var catsHotdog = []string{
emoji.GrinningCat.String(),
emoji.GrinningCatWithSmilingEyes.String(),
emoji.CatWithTearsOfJoy.String(),
emoji.SmilingCatWithHeartEyes.String(),
emoji.CatWithWrySmile.String(),
emoji.KissingCat.String(),
emoji.WearyCat.String(),
emoji.CryingCat.String(),
emoji.PoutingCat.String(),
emoji.HotDog.String(),
}
var CATS_HOTDOG = ToEmojies(catsHotdog)
It doesn't even have to be from the emoji-package,
simply make a slice of your desired emojies, and use the ToEmojies
-func.
Then provide this as an argument in moths.OptionWithEmojies(CATS_HOTDOG)
when calling the moths.NewMoths()
.

sample ๐ค
history โ
future ๐ฎ
- Rename
moth
to something better (OTP
/ Token
)
- Add better documentation
- Rename the
gen
-variable to otp
- This means renaming the
otp
-package as well?
- Make a fiber version
- Get pkg.go.dev up-to-date
