Is it possible to conceal the mapbox access token during the map initialization process?

I have successfully integrated the mapbox API to create an interactive map on my website. To ensure the security of my access token, I have set up a proxy to handle the API requests externally. However, I am facing a challenge when it comes to hiding the access token during the initialization of the map on the client side.

The current code snippet initializes the map as intended, but I am concerned that anyone inspecting my code in the browser or viewing it on GitHub will be able to access my token:

const accessToken = 'myKey';

mapboxgl.accessToken = accessToken;
const map = new mapboxgl.Map({
    container: 'map',
    style: 'mapbox://styles/mapbox/streets-v12',
    center: [-46.625290, -23.533773],
    zoom: 12,
    minZoom: 5,
    language: 'pt'
});

Although I have restricted the access token to specific URLs, I am unsure if this provides adequate protection for my token.

If you have any suggestions or solutions to help secure my access token, please feel free to share them. Thank you!

Answer №1

You may not be able to hide it completely, but if we're talking about your pk.ey... token (which is not a secret one), then that's pretty standard.

In theory, someone could potentially gain access to some data using your token and you could be held responsible for any unauthorized usage. However, in reality, this doesn't seem to be a common occurrence. To mitigate the risks, consider rotating your token frequently through the API.

The code I'm using to initialize the map functions properly, but if someone were to inspect my code in the browser or view it on GitHub, they would be able to see the token.

There's no need for them to go through those lengths - simply looking at the network tab will reveal your token in every network request made.
