Sentinel Authenticator Icons

This repository contains all the icons available within the Sentinel 2-Factor Authentication app.

A lot of icons are already present, but if you are missing one you can either:

• open an issue here and I'll try to add it as soon as possible
• create a pull request submitting your icons

---

How to add a missing icon?

It's super simple, here are the requirements:

• icons must be in .png format
• icons must be of squared size (400x400 preferred size, do not submit huge images to avoid slow load times)
• icons name must be lowercase

How to submit your icon?

1. Insert the icon in the /icons/assets/ folder
2. Add a row in the /icons/index.json referenced to the icon (check the following section to understand how the algorithm works)
3. Submit a pull request

How does the algorithm work?

The index.json is structured in this way

<issuer>: <name of the icon without extension>

an example is the following where we have 2 issuers pointing to the same icon.

"binance": "binance",
"binance.us": "binance"

The app will take the issuer and apply

• a lowercase()
• a replace('.com','')
• a trim()

before trying to match the resulting string with a key of the index.json.
If the attempt fails, it will try to split() the issuer on the blank space, take the first substring and try to match it again.

See an example

Issuer = "Binance US.com"

1st Attempt

lowercase() + replace('.com','') + trim()
Resulting Issuer = "binance us"
The match will fail ❌, no key was found in index.json.

2nd attemp

split(" ")[0]
Resulting Issuer = [binance, us] -> "binance"
Match found ✅! The correct icon will be displayed.
