# Tiktok Passport

Minimal (really, 6 megabytes) docker image that signs Tiktok requests. For now,
it works for my use case. You will have to spin up a pool of selenium
instances.

Tiktok Passport automatically recovers from connection-related failures with
the remote browser. Just make sure to monitor and restart unhealthy/crashed
selenium instances.

To prevent detection, [evasion strategies](https://github.com/kandayo/tiktok-passport/tree/main/src/tiktok_passport/marionette/javascript/evasions)
ported from `puppeteer-extra-plugin-stealth` are included. You can find the
stealth test at the examples folder.
