Troubleshooting Login Issues (Wrong Credentials, Blocked Access, etc.)
Having trouble logging in to your markto.ch account? Most login problems fall into a few common categories: incorrect credentials, verification issues, temporary blocks, browser/device problems, or account-specific restrictions. This guide walks you through the most frequent issues and their fixes — in order of what to try first.
1. “Invalid Email or Password” / Wrong Credentials Error
- Double-check your email address:
- Make sure there are no extra spaces before/after.
- Check for typos (e.g., @gamil.com instead of @gmail.com).
- Emails are not case-sensitive, but confirm it matches exactly what you registered with.
- Verify your password:
- Check Caps Lock is off.
- If you use a password manager, copy-paste it to avoid typing errors.
- Try typing the password in a plain text editor first to confirm it’s correct.
- Best next step: Click Forgot Password? on the login page and follow the reset process (see our article: “Forgot Password? How to Reset Your Password Step-by-Step”).
2. No Verification Code Received (Email or SMS)
- For SMS (phone verification):
- Confirm your phone has signal and is not in airplane or Do Not Disturb mode.
- Check the number format — use full international format if prompted (+41 for Switzerland).
- Request the code again (usually a “Resend” button is available).
- Wait 1–2 minutes — delays can happen during high network traffic.
- Try a different mobile network or restart your phone.
- For email verification:
- Check all folders: Inbox, Spam/Junk, Promotions (Gmail), Updates, Social.
- Search your inbox for “markto”, “verify”, or “code”.
- Add [email protected] (or similar) to your contacts/safe senders list.
- Request a new code via the “Resend” option.
- If both fail: Log in from a different device or network (e.g., switch from Wi-Fi to mobile data).
3. Account Temporarily Blocked or Locked (“Too Many Attempts”, “Account Blocked”)
- This usually happens after 5–10 failed login attempts in a short time (anti-brute-force protection).
- Solution:
- Wait 15–60 minutes — most temporary locks expire automatically.
- Do not keep trying during the lockout (it may extend the time).
- After the wait, try logging in again with correct credentials.
- If still blocked after waiting: Use the “Forgot Password?” flow to reset and regain access.
- Permanent blocks are rare and usually only occur for repeated serious violations (e.g., spam, scams) — see section 7 below.
4. Browser or Device-Related Problems
- Clear your browser cache and cookies:
- Chrome: Settings → Privacy and security → Clear browsing data → Cookies & cache.
- Firefox/Safari: Similar steps under Privacy or History.
- Try these alternatives:
- Open an Incognito / Private browsing window.
- Use a different browser (e.g., switch from Chrome to Firefox).
- Try logging in from another device (phone, tablet, different computer).
- Disable browser extensions temporarily (ad blockers, VPNs, privacy tools can interfere).
- Make sure your browser is up to date.
5. “Account Already Exists” or Redirect Loops
- If you see “Account already exists” when trying to register again:
- You likely already have an account — go back to the login page and sign in instead.
- If login redirects you in a loop:
- Clear cookies/cache (as above).
- Log out completely if partially signed in.
- Try from incognito mode or another browser.
6. Two-Factor Authentication (2FA) Issues (If Enabled)
- If you set up 2FA but no longer have access to the phone/app:
- Use any backup codes you saved during setup (check your email or secure notes).
- If no backup codes: Contact support immediately (see below) — they can help verify your identity and disable 2FA temporarily.
7. Suspected Account Suspension / Ban
- If login fails with a message like “Account suspended”, “Access denied”, or “Violation detected”:
- This usually means the account violated community guidelines (e.g., prohibited items, spam, scam reports, multiple fake accounts).
- Check your registered email for any notification from markto.ch explaining the reason.
- To appeal or get clarification:
- Use the “Contact” or “Support” link at the bottom of the website.
- Submit a polite appeal with your email, username (if known), and explanation.
- Note: Serious violations (fraud, illegal content) may result in permanent bans with no appeal.
8. Still Can’t Log In? Contact Support
If none of the above resolves the issue:
- Go to the markto.ch homepage → scroll to the footer → click Contact, Support, or Hilfe.
- Provide:
- The email address associated with the account
- A description of the exact error message
- What steps you’ve already tried
- Your device/browser details (optional but helpful)
- Response times are usually within 1–3 business days.
Quick Summary – Try in This Order
- Check email/password spelling & Caps Lock
- Use “Forgot Password?” to reset
- Clear cache / try incognito / different browser/device
- Wait out any temporary lock (15–60 min)
- Check spam folders for verification emails
- Contact support only after exhausting the above
Most login issues are solved within minutes by resetting the password or clearing browser data. Once you’re back in, consider updating your password and reviewing security settings for extra protection.
