Below are answers to frequently asked questions about Blue Kik in regards to the Log In, Sign Up, and access token processes.
Kik has introduced a new access token protocol. This protocol requires the app to "check in" once per hour, and pass invisible challenges.
Kik's goal with this was to block spam bots and any other clients not approved by Kik.
Sometimes, you may get a popup related to a token error and prompted to restart.
The reason this usually happens is because when the app is in the background, Android tends to restrict CPU or network usage, causing the app to stall when solving the challenge, and show the error as a fallback mechanism.
For a few months, Kik has been rolling out changes to the login and sign up systems to add new security measures and protections.
To enforce this, they methodically disabled old versions and ultimately disabled the old method of registering, and as of 9/9/24, going through the new system is required.
The new security systems are designed to block bots, spam, mods, or anything that isn't an official device running the official app from proceeding.
Since it was introduced a few months ago I have been analyzing the app and working on ways to enable Blue Kik to continue.
As of 9/10/24, Blue Kik is capable of logging in and signing up as normal.
In many cases, where registration is blocked on the Play Store version, Blue Kik will work.
Please see the below items for information about rules in related to the service.
We aim to support as many Android devices as possible. Note that emulators are not officially supported, and may be disallowed from some features.
We understand that to many, unlocking your BL to flash custom ROM means freedom.
Blue Kik supports most custom roms and some rooted devices, as long as root is not used to tamper with Blue Kik.
Kik uses Play Integrity to try and detect rooted devices, emulators, and unofficial apps.
In April 2025, Kik blocked rooted/unlocked devices by requiring the MEETS_DEVICE_INTEGRITY verdict.
This has the side effect of blocking custom roms without root, such as GrapheneOS.
GrapheneOS supports verified boot attestation and there is no good reason for Kik or Google to be blocking it.
To make the service available to all users, please respect the following rules:
Captchas were added by me to protect my resources from bad actors and allow as many real (human) users to get in as possible.
Without such protections, people will attempt to script your app with which causes a wrongful allocation of resources.
This makes it much harder to do so, as anyone smart enough to do this should be smart enough to beat the protection on their own.
If you have trouble solving it, close the window by using the 'back' key and try again.
The new methods require occasional adjustments. To be able to accomplish this, it requires specialized setups, servers, etc which cost money to operate.
To allow as many users to be able to access the app as possible, some rate limiting must be introduced.
Without such protections, spammers attempt to abuse your service via automation or other means and they will ruin it for everyone else if left unchecked. Therefore, it is necessary. I am always looking at ways to make it as unobtrusive as possible and improve this.
Try the following:
No. The service was designed with privacy in mind, so the username / email / password / birthday / display name is never sent to the server and therefore no decisions can be based on it.
Sometimes, as necessary, the app will route some traffic through my servers to complete the request. This is only done when the server determines that it won't work otherwise.
All such connections are end to end encrypted with certificate pinning protection to prevent snooping by me or anyone else.
This error occurs on the unmodified versions of Kik (from Play/App store)
Here are a list of reasons you can get this error:
This happens when you have a bad reCAPTCHA risk score.
This can happen when a fake device is detected, or something about your behavior or connection is suspicious.
