"Secure communication is integral
to NoLag, not an afterthought"

Access Tokens

One of NoLag's fundamental features is data security. Security, in this context, means ensuring that the right data is delivered to the intended destination.

Our Device Tokens empower you with precise control over the access levels granted to each Device Token.

Device Tokens can be managed either through the NoLag portal or via API calls.

All Device Tokens are bound to a specific Tunnel and cannot be used outside of their designated Tunnel.

Device ACL capabilities

    Define the extent of access a device possesses within the associated Tunnel.

    Pub/Sub Permissions:
    • Full Access: Devices can both Publish and Subscribe to Topics.

    • Publish-Only Access: Devices can only Publish to Topics.

    • Subscribe-Only Access: Devices can solely Subscribe to Topics.

  • Token expire:

    Set how long a token is valid for in seconds

  • Default Topics and identifiers
