Two-Factor Authentication — Help

This page completes the second step of signing in by validating a one-time code sent to your email.

Read the instructions below to finish signing in, resend a code if needed, and recover from common problems.

What this page does

• Shows a masked version of your email (so you can confirm where the code was sent)
• Lets you request a one-time verification code to be sent to that email
• Lets you enter the code and validate it to finish signing in
• Provides a Sign Out button to cancel and return to Sign In

Before you start

• Make sure you started sign-in and are using the same browser/session where you entered your password.
• Do not refresh the page or use the browser Back button while completing 2FA — doing so may expire the session and require you to sign in again.

Step-by-step: validate the code

1. Click Send Code (if the code hasn’t already been sent).
2. Check the email shown (masked) for a message from KNEWTE with the verification code. Check Spam/Junk if you don’t see it.
3. Enter the code into the Enter Code field exactly as shown in the email.
4. Click Validate.

• On success you will be signed in and redirected to your dashboard.
• On failure you will see a message telling you the code is invalid or expired.

Timing and limits (important)

Code lifetime

• The verification code expires after about 5 minutes. If expired, click Send Code to get a new one.

Resend cooldown

• After sending, the Send Code button is temporarily disabled for ~2.5 minutes.
• A countdown timer appears showing when you can resend.

Resend / attempt limits

Repeated resends and failed validation attempts are limited for security:

• Excessive resends or failed attempts can eventually block your account.
• If you reach the maximum failed attempts (5), your account will be blocked and you will not be able to sign in until the block is cleared by the service (contact support).
• If your account is already blocked, the page will show a clear message and disable the controls.

Messages you may see and what they mean

• “Please enter the code.” — you submitted without typing a code.
• “No verification code found. Please resend a new code.” — there is no active code stored; click Send Code.
• “The code has expired. Please resend a new code.” — the code timed out; click Send Code.
• “Invalid code. Please try again.” / “Invalid code. X more attempts left…” — code mismatch; retype carefully. Repeated failures may block your account.
• “Verification code sent.” — a code was sent to your email (also shows warnings if resends are limited).
• “Your account has been blocked after 5 failed attempts.” — your account is locked for security after multiple failed tries.

If a resend is blocked you’ll see a countdown

After you request a code the Send Code button is disabled and a countdown label appears (for example: “Resend the code in Xm Ys”).

When the timer ends the page refreshes or you can click Send Code again.

Security & privacy tips

• Treat the verification code like a password — do not share it.
• Only request codes when you are actively signing in.
• If you receive a 2FA code you did not request, do not use it and contact support.

Troubleshooting checklist

No email received

• Check Spam/Junk folder.
• Confirm you signed in with the correct email address.
• Wait a minute and click Send Code again after the cooldown.

Code expired before you could use it

• Click Send Code to get a new code and use it within 5 minutes.

Typing mistakes

• Copy/paste the code from the email if available (avoid extra spaces).
• Enter digits exactly as shown.

Repeated failures / blocked account

• If your account becomes blocked, contact support and provide account email and the approximate time you were blocked.

Expect identity verification steps to restore access.

Session expired or page shows session missing

• Sign in again from the Sign In page; the 2FA session is temporary and must match the original sign-in attempt.

Other controls

• Sign Out: cancels the 2FA flow, clears the temporary session data and returns you to the Sign In page.
• If you have previously set account recovery options (security questions), you may be redirected to those flows at sign in — follow the on-screen guidance.

Accessibility & keyboard tips

• All controls are keyboard accessible: use Tab to move focus and Enter/Space to activate buttons.
• The masked email helps you confirm delivery without revealing the whole address.

If you need help

Provide support with:

• the email you used to sign in
• a screenshot of the page and message shown
• the exact time you attempted sign in

This helps them investigate code delivery and account state.
