# Fix sign-in problems

Can't sign in to Klarity? Before assuming an outage, know that most blocks come from a wrong password, an email not yet verified, or a temporary limit after several attempts. Here are the most frequent causes, and how to clear them one by one.

# Understanding the sign-in screen

You sign in with your **email address** and your **password**. Until your email is verified (brand-new account), access to the app stays limited. And to protect you, Klarity temporarily blocks sign-ins after too many failed attempts.

| Good to know: the session refreshes automatically in the background. You don't have to sign in again on every visit as long as you stay active.

# Possible causes and solutions

1. **Incorrect credentials** — double-check the email and password, watching for capital letters and extra spaces.
2. **Forgotten password** — click **Forgot password?** on the sign-in screen, enter your email and follow the reset link you receive (remember to check your spam folder).
3. **Too many attempts** — after several failures, access is temporarily limited (message **Too many attempts**). Wait a few minutes before trying again.
4. **Unverified email** — if your account is recent, first open the verification link received at sign-up. Need to receive it again? Use **Resend verification email**.

|| If you changed your email recently, sign in with the **new** address once the change is confirmed — the old one no longer works.

# Still blocked

- Try **another browser** or a **private browsing** window to rule out a cache issue or an extension.
- Check your **internet connection**: Klarity shows an **Offline** indicator when the connection is down.

| 💡 **Tip:** if the reset or verification link says it's "invalid or expired," it has already been used or is too old. Just request a new one.
