Captcha issues blocking login, downloads, or subscriptions

Last updated: October 16, 2026

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

Seeing “Captcha error. Please try again.”, a challenge that won't load, or a completed captcha that still blocks your account action? Captcha guards account creation, password resets and verification-email requests against spam and automated abuse.

Quick checks

  • Repeated attempts: “Too many attempts — please try again later.” clears on its own — allow up to 30 minutes for resets and resends, an hour for repeated sign-ups, one minute for network limits. Shared networks and VPNs reach limits sooner, and switching networks doesn't clear email limits.

  • Outages: A temporary verification or service outage clears with waiting — don't retry repeatedly or change your password.

  • Browser test: Try the same action at wisprflow.ai. If it also fails there, the problem isn't confined to the desktop app.

After each change below, retry your action. If it completes, stop; otherwise continue.

Mac and Windows

Flow opens your default browser. Sign-up always shows a captcha; password sign-in, resends and forgot password show one only if automated activity is suspected. Every attempt resets the captcha, and a failed captcha prevents account creation or email sending.

Note: Finish browser sign-in within 5 minutes; after that, click Sign in again. Emailed sign-in links can complete the attempt for 15 minutes total, even after you reopen Flow. If the browser never opens, click Sign in again; dropped connections retry automatically within the 5-minute window.

  1. Disable script-blocking extensions.

  2. Try a different browser.

  3. Clear cache and cookies for wisprflow.ai.

If browser checks don't help

Restart and update Flow:

  1. Quit Flow — Mac: click the Flow icon in the menu bar, then Quit Flow. Windows: right-click the Flow icon in the system tray and select Exit.

  2. Reopen Flow and update when prompted, or follow How to update to the latest version.

Web captcha and resend messages

“Please complete the captcha.” and “Captcha expired. Please complete it again.” both need a fresh challenge. For “We couldn't verify you're human. Please try again.”, retry without reloading the page.

Other resend or reset-email errors aren't always captcha failures. A successful resend disables “Verification email sent” for 30 seconds. If your email is already verified, enter your password instead of resending.

iOS

The captcha starts automatically on the sign-up, forgot-password and resend-verification screens and disappears once you complete it. There's no captcha on email entry, password sign-in, Google, Apple, Microsoft or SSO.

Create account, Send reset email and Resend verification email stay disabled until the captcha is complete; creating an account also needs your email, password and full name. Sign In on the resend screen stays enabled.

Switching between the sign-up, resend-verification and reset-password screens — including Forgot password — resets the captcha, so complete the challenge again. After you create an account, verifying your email signs you in automatically unless you leave the screen.

  1. Open the App Store and tap your profile icon in the top right.

  2. Update Wispr Flow if an update is available.

  3. Reopen Flow and retry the action.

Challenge errors

Messages below the fields identify what failed: “Verification challenge failed” (the challenge), “Network error during verification” (your connection), “Verification cancelled” (closed or timed out — the button stays disabled), and “Unable to initialize verification” (the challenge couldn't start). “Verification failed. Please try again.” covers a missing completion or other failures; an incomplete captcha prevents submission.

Verification unavailable before email entry

If “Verification service unavailable. Please try again later.” and “Please try a different sign-in method.” replace the email and password screen:

  1. Tap Go Back.

  2. Choose your account's Google or Apple sign-in; More Options reveals Microsoft, SSO and Email.

Android

Android sign-up and sign-in never show a captcha, so captcha isn't the cause. Emailed sign-in and verification links work for 30 minutes after you start the sign-in, sign-up or resend in the app; tap one later and it's refused — start sign-in again and open the newest email. Contact support for other login or sign-up problems on Android.

Email addresses the captcha path rejects

Important: Use an address with at least one letter before the @. Choose carefully — the email address and sign-in method on an account can't be changed later.

Only digits before @

These addresses are rejected at account creation and at password resets that require a captcha. “Invalid email address.” reflects Flow's spam restriction, not a formatting problem.

Every sign-up path is affected, including Continue with Google, Apple and Microsoft: the provider signs you in, account creation rejects the address, and you return to the sign-in page with either “Invalid email address” or “Authentication failed,” depending on the browser. Another browser, cleared cookies or a private window won't change the outcome.

Aliases containing +

New email and password accounts reject “+” aliases on the web page before the password and captcha step. Existing aliases work in standard sign-in, and Google, Apple, Microsoft, SSO and IT-managed accounts are exempt. Enterprise web password sign-in also rejects existing aliases; SSO is unaffected.

Password-reset links

Reset and emailed sign-in links expire 15 minutes after the email is sent. If a link is dead, the reset page replaces the password form with “This link has expired”, “This link has already been used” or “This link is invalid or has expired”, plus an email field and a Send a new link button.

Important: Resetting your password signs you out on all devices, and a reset error can appear after the password has already changed — try signing in with the new password before retrying.

  1. Enter your email on that page and click Send a new link.

  2. Open the new email and set your password — it must be at least 8 characters, or you'll see “Password must be at least 8 characters.”

  3. Sign in again with the new password.

Resend messages tell you what to fix: wait and try again if you've requested too many links, or correct the address if it's reported as invalid. If the resend fails outright, try another browser or clear wisprflow.ai cache and cookies, then retry. A successful request doesn't guarantee the email arrives; request another if it doesn't.

Still stuck?

Contact support if:

  • The captcha still fails after these checks.

  • The captcha completes but your action doesn't go through.

  • Sign-in fails after a team invite.

Include your platform (Mac, Windows, iOS or Android), device, the action you were taking, the exact message, a screenshot, what you tried, and your invite link if relevant.
