Common Questions
Q: What does "Invalid CSRF token" mean?
A: CSRF stands for Cross-Site Request Forgery. AXP uses a hidden security token to verify that login requests genuinely come from you. If that token is missing, expired, or doesn't match — for example, after you've cleared your cache or had the login page open for a long time — you'll see this error. It's a security feature, not a bug, and doesn't mean your account has been compromised.
Q: Why does signing in with Google still work when I get this error?
A: Google's sign-in flow uses a separate authentication process that doesn't depend on the same browser token. So even if the standard SSO login triggers this error, clicking Sign in with Google on the same screen will typically succeed.
Q: Do I need to clear all my browser cookies to fix this?
A: No — you can clear cookies just for alliants.app. In Chrome, press Esc → Third-party cookies → See all sites and permissions, then find and remove alliants.app. This targets only the AXP session without affecting your other sites.
Q: What causes this error in the first place?
A: The most common triggers are:
Clearing your browser cache or cookies
Having the login page open for a long time before submitting
Being logged into AXP across multiple tabs at the same time
A browser extension (such as an ad blocker or privacy tool) interfering with cookies
Q: What if none of these steps work?
A: Try logging in via an incognito/private window or a different browser entirely. If you're still unable to access AXP, contact your property's system administrator or reach out to AXP support.
