Captcha issues blocking login, downloads, or subscriptions

Last updated: July 14, 2026

Available on: Mac, Windows, iOS. Android sign-up and authentication are fully supported but don't include a captcha challenge.

If you're seeing "Captcha error, please try again," a captcha that won't load, or a captcha that appears checked but doesn't let you proceed — this guide will help you fix it. Most issues resolve in under 2 minutes after updating Flow.

Note: Captcha is only required when creating a new account, resetting your password, or resending a verification email — not when signing in to an existing account. If you're having trouble signing in to an existing account, the issue is not captcha-related.

Quick checks

Is Flow up to date? Several captcha bugs were fixed in recent versions — updating resolves most issues.
Have you tried several times in a row? Sign-up, password reset, and resend verification are rate-limited. If you hit the limit, wait a while and try again — you'll see "Too many signup attempts. Please try again later."
Are you on a shared network or VPN? VPN or shared network users may hit rate limits sooner. Wait a few minutes, or switch networks, and try again.
Is your network on your organization's allowlist? If your organization restricts access by IP, you'll be automatically signed out and then see a blocked screen titled "Your network isn't allowed" in place of the sign-in form. The screen has both a Retry button and a Sign Out button. Switch to an approved network or contact your admin. Once you're back on an approved network, Flow will detect it on the next successful request and dismiss the block automatically.
Does captcha work in a browser? Try completing your action at wisprflow.ai. If captcha fails there too, the issue is network-related, not Flow-specific.

How to fix this

Note: On Mac and Windows, Flow opens your web browser to complete sign-up, password reset, and verification. Captcha challenges appear in the browser, not in the Flow app. If you take a few minutes to complete sign-in in the browser, Flow will still receive your sign-in when the browser callback completes. If too much time passes, return to Flow and click Sign in again.

Mac

Quit Flow completely — click the Flow icon in the menu bar, then click Quit Flow.
Reopen Flow.
Update to the latest version when prompted. If you're not prompted, follow How to update to the latest version.
Retry your original action (creating an account, resending a verification email, or resetting your password).

If captcha loads and you can complete your action, you're done. If not, see "If updating didn't help" below.

Windows

Close Flow completely — right-click the Flow icon in the system tray and select Exit.
Reopen Flow.
Update to the latest version when prompted. If you're not prompted, follow How to update to the latest version.
Retry your original action (creating an account, resending a verification email, or resetting your password).

If captcha loads and you can complete your action, you're done. If not, see "If updating didn't help" below.

iOS

On iOS, the captcha appears directly on the sign-up, forgot password, and resend verification screens. You must complete it before proceeding.

Open the App Store and tap your profile icon in the top right.
Update Wispr Flow if an update is available.
Reopen Flow and retry your action.

If captcha loads and you can complete your action, you're done.

If the captcha can't load, you'll see an error screen with the message "Verification service unavailable. Please try again later.", a hint "Try a different sign-in method", and a single Go Back button. Tap Go Back to return to the main sign-in screen and use Google, Apple, Microsoft, or SSO instead — these don't require captcha. Google and Apple appear by default; tap More Options for Microsoft, SSO, or email sign-in.

If the captcha challenge fails after loading (for example, you didn't complete it in time or your network dropped mid-challenge), you'll see an inline message "Verification failed. Please try again." — just try the challenge again.

Note: Android sign-up, forgot password, and email verification screens don't currently include a captcha challenge. If you're having login or sign-up issues on Android, contact support — the issue is unrelated to captcha.

If updating didn't help (Mac and Windows)

If captcha still fails after updating Flow, the issue is likely in your web browser. Flow opens the sign-in page in your default browser for authentication.

Clear your browser cache and cookies for wisprflow.ai.
Disable browser extensions that block scripts, such as ad blockers and privacy extensions.
Try a different browser.
Retry sign-up or password reset.

If captcha completes and your action goes through, you're done.

Note: If the connection between Flow and your browser drops during sign-in, Flow reconnects automatically. If the browser doesn't open at all when you click Sign in, click Sign in again to retry.

Common issues

Captcha unavailable error appeared silently with no message (iOS)

In earlier versions of Wispr Flow for iOS, if the captcha service was unavailable during sign-up or onboarding, the app could fail silently — leaving you stuck with no explanation. This is fixed in recent versions. You will now see an error screen with a Go Back button so you can retry or choose a different sign-in method.

Update Wispr Flow to the latest version from the App Store.
Reopen the app and try again. If the captcha service is unavailable, you'll now see a clear error screen.

Captcha appears checked but the button stays disabled (iOS)

This was caused by the captcha state not resetting when navigating between the sign-up, forgot password, and resend verification screens. Fixed in recent versions of the Wispr Flow iOS app.

Update Wispr Flow from the App Store.
Reopen the app and try again.

FAQs

Why am I seeing a captcha?

Captcha verification is required when creating a new account, resending a verification email, or resetting your password. This prevents spam and automated abuse.

Does Android require captcha?

No. Android sign-up and authentication screens don't currently include captcha verification.

Can I sign up with an all-numeric email address (e.g., 123456@domain.com)?

No. Email addresses where the part before the @ is entirely numbers are not accepted, and you'll see "Invalid email address." Use a standard email address instead.

Can I sign up with an email alias like name+tag@domain.com?

No. Email addresses containing a + are not accepted for sign-up, and you'll see "Email aliases (containing +) are not supported. Please use your original email address." Use your base email address (without the +tag) instead.

What if my organization uses SSO?

If your organization uses SSO, you must sign in through SSO. Google, Apple, or Microsoft sign-in will redirect you to an error page explaining that SSO is required for your domain. SSO enforcement only applies when the organization has an active subscription. If your organization uses directory sync to manage accounts, you may see "Account Managed by Your Organization" instead — contact your IT admin to be provisioned.

SSO-related error pages you may encounter:

SSO Sign In Required: your domain requires SSO.
Account Managed by Your Organization: your account is managed by your organization — contact your IT admin.
SSO Requires Being A Part Of An Organization: your domain is not in any organization.
Your Organization Has Not Configured SSO: your admin needs to complete SSO setup.
You were not invited to this organization: membership issue — contact your IT admin.
