receiving an initial request to download a digital asset to the computing device via the web browser;

sending the digital asset to the computing device in conjunction with the customized digital font unique to the computing device; and

in response to authenticating the computing device based on the customized digital font unique to the computing device, providing access credentials to the computing device that provide access to one or more features of the digital asset at the computing device.

4. The method of claim 1, wherein determining that the textual element rendered by the computing device via the web browser uses the customized digital font further comprises:

applying the optical character recognition algorithm to the image to identify characters of the textual element rendered by the computing device via the web browser; and

comparing the identified characters of the textual element with the reference text.

5. The method of claim 3, wherein authenticating the computing device based on the computing device utilizing the customized digital font further comprises:

determining that the computing device has the digital asset and that the textual element rendered by the computing device uses the customized digital font unique to the computing device.

6. The method of claim 1, wherein authenticating the computing device based on the computing device utilizing the customized digital font further comprises:

comparing a width of the textual element rendered by the computing device with a width of a second textual element.

7. The method of claim 1, wherein authenticating the computing device based on the computing device utilizing the customized digital font comprises:

sending an additional request to the computing device to render a second textual element utilizing the customized digital font;

detecting the second textual element rendered by the computing device; and

comparing the textual element and the second textual element.

8. The method of claim 4, further comprising:

upon generating the customized digital font, applying the customized digital font to a text to create a numerical font-based client identification.

9. The method of claim 8, further comprising:

determining that the textual element rendered by the computing device uses the customized digital font by determining a correspondence between the numerical font-based client identification and the textual element rendered by the computing device.

10. The method of claim 7, wherein the additional request comprises one or more requests to render the second textual element utilizing a digital asset on the computing device, wherein the digital asset is not the web browser.

11. The method of claim 10, wherein the client information comprises at least one of:

state information regarding one or more digital assets on the computing device;

one or more updates available for the one or more digital assets on the computing device;

access credentials;

payment information;

or demographic information.

12. A system comprising:

at least one server device; and

at least one non-transitory computer readable storage medium storing instructions that, when executed by the at least one server device, cause the system to;

generate, by the at least one server device storing client information corresponding to a computing device, a customized digital font unique to the computing device for authenticating the computing device by changing a first character order of a base digital font to a second character order specific to the computing device;

send the customized digital font from the at least one server device to the computing device;

upon receiving, by the at least one server device, a request for the client information from the computing device, authenticate the computing device based on the customized digital font by;

sending a second request to the computing device to render a textual element utilizing the customized digital font;

identifying the textual element by capturing an image of the textual element rendered by the computing device via a web browser; and

determining that the textual element rendered by the computing device via the web browser uses the customized digital font by applying an optical character recognition algorithm to the image of the textual element rendered by the computing device and comparing the textual element with a reference text generated utilizing the customized digital font; and
