# Signing in and security

> Fixes for sign in with email and password, confirmation and reset links, closed registration and expired sessions.

Streaming Classic signs you in with email and password. Confirmation and reset links expire, and so does a session after inactivity.

<AccordionGroup>
  <Accordion title="I cannot sign in" icon="log-in">
    **"These credentials do not match our records."** means a wrong email or password, so reset your password if needed. **"Please confirm your email address before signing in."** means you still need to click the link in your confirmation email.
  </Accordion>

  <Accordion title="Too many login attempts." icon="hourglass">
    For safety, sign in is limited after several wrong tries. Wait about a minute, then try again or reset your password.
  </Accordion>

  <Accordion title="My confirmation link does not work" icon="mail-warning">
    **"This confirmation link has expired. Request a new one."** or **"...invalid or already used..."** means the link is no longer valid. Use **Resend confirmation** on the sign up page, or simply sign in if your account is already confirmed.
  </Accordion>

  <Accordion title="My password reset link does not work" icon="key-round">
    **"This reset link is invalid or expired."** means the link is too old. Request a new password reset from the sign in page.
  </Accordion>

  <Accordion title="Registration is currently closed." icon="user-x">
    Sign up is paused for now. Contact your administrator or support if you need an account.
  </Accordion>

  <Accordion title="My session expired" icon="clock">
    **"Your session has expired. Please sign in again."** appears after a period of inactivity. Sign in again to continue.
