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.

In most cases, Blue Kik can fix this problem and support custom roms.

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:

• Do not spam the service.
• Once you create an account or sign into an account, stay logged in for at 1-2 days. Not doing so may cause rate limits to be hit.
• When logging in, please make sure that the username and password is valid. If it isn't, reset it here.

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 (lesson learned the hard way).

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:

• Log in on a genuine Android device rather than an emulator
• Avoid using cloner or dual space apps
• Disable your VPN temporarily (you can turn it back on after logging in)

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 as a means to make it work properly and to anonymize you.

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:

• Your IP address is banned or rate limited by Kik (limits are ~3 registrations per IP per 24 hours, ~10 logins per 24 hours)
• Your device is banned (by Android ID)
• Your device is rooted (unlocked bootloader) or an emulator
