X users hit by “Attestation Denied” login error: What you can do

Update 01/12/25 – 10:30 am (IST): NeoFreeBird has confirmed that the previous password reset method no longer works to bypass the “Attestation Denied” error. More details here.

Update 06/11/25 – 01:10 pm (IST): X appears to have disabled the “Sign in with username” login flow across official clients, which undercuts the NeoFreeBird 2.2 method that explicitly relied on that exact screen to get past the attestation-related login roadblock, making that route unreliable now.

This change indicates X is actively closing previously viable sign-in paths leveraged by third‑party builds, so expect further churn around login flows until a more stable approach emerges.

Meanwhile, some users are even reporting the same problem with the X-Lite app.

Update 03/11/25 – 09:05 am (IST): While there’s still no official word about the issue, the developer of NeoFreeBird has confirmed that the latest NeoFreeBird 2.2 for Twitter 11.35 update brings a fix. They said, “Make sure it says “Sign in with username” and not just “Sign in” when you log in. Restart the app a few times if it doesn’t.”

As for affected users who aren’t using any modded apps, the password reset method mentioned below is still the only reliable solution, according to multiple user reports.

So you’re sitting there with your phone, you open X, type in your login info, and suddenly you’re staring at this annoying “Login Error: Attestation Denied” message. Just like that, you’re locked out. This thing has been hitting both Android and iOS users lately, and sometimes it even throws a bunch of random numbers at you before shutting you out completely.

People started complaining about this issue over the past couple of days. The common story goes like this: you’re either suddenly logged out for no reason, or you’re trying to add another account and it just won’t let you. One person mentioned they couldn’t log into a fourth account on mobile, which is weird because X supposedly lets you handle up to ten accounts. Another user tagged Musk on X for help.

This issue seems especially bad for modded apps. If you’re using something like ReVanced tweaks, you’ve probably noticed login problems across different versions. Even third-party apps like NeoFreeBird are getting hit with the same denial error, whether you’re on a new build or an older one.

Nobody’s quite sure if this is X cracking down on purpose or if it’s just a bug in their system.

The complaints on X itself are piling up fast. You’ve got people even begging support for help. Everyone’s sharing their stories about what used to be a simple login suddenly becoming impossible. Some users are even warning others not to log out at all if you want to avoid the headache.

From what people who’ve dug into the code are saying, this probably has something to do with X tightening up their app verification process. According to one person who claims to be in a group chat with some X devs, the backend is now checking for modified devices or apps, especially ones with root access or custom modifications.

But here’s the weird part: even people with completely clean setups are getting blocked. It could be from using a VPN, running outdated software, or maybe having too many accounts logged in. There’s a lot of discussion about this in various threads.

Alright, here’s what you can actually do about it. First thing: skip the app entirely and just log in through your browser, either on your phone or computer. The web version doesn’t have the same strict checks, so you should be able to get in without any problems. Once you’re in, change your password right away, then try logging into the app again with your new password. This works especially well if you’ve got two-factor authentication turned on. A lot of people say this fixed it for them.

Next up, clear the app’s cache or just delete it completely and download it fresh from the app store. Turn off any VPNs or proxies you might be running because those can trigger the error. If you’re using a modded app like ReVanced, you could try rolling back to an older version like 10.48.0, though honestly, switching to the official app might save you a lot of hassle. If none of this works, you can contact X support, but fair warning: their response times aren’t great.

There’s still no official statement from xAI about any security tweaks behind the scenes, so take this information with a grain of salt. We’ll post an update if and when there’s something to share.
