Password Reset Modal

A password reset request modal with a signature Corner Slide-and-Spin entrance — the modal slides in from bottom-right with subtle rotate + scale, feeling like a helpful assistant materialized rather than a distant modal. Email input for reset link + "Send reset link" CTA + "Return to sign in" link + help microcopy for account recovery. Medium intensity — auth flows are personal but not compliance-heavy.

How this works

The signature entrance is Corner Slide-and-Spin: modal starts at opacity: 0, transform: translate(24px, 32px) rotate(3deg) scale(.96) with transform-origin: bottom right. Animates to settled state via cubic-bezier(.34, 1.36, .44, 1) over 400ms — subtle overshoot that feels warm and personal (like a helpful chat bubble arrived). Same technique as Demo #01 Confirm Delete but with different palette + content — proving the entrance library reuses across contexts.

Medium intensity because password reset is a personal + slightly stressful moment (user locked out) — warm and reassuring entrance matches the emotional context. NOT full intensity (bouncy elastic feels wrong when user is frustrated). Blue-tinted palette (#3b82f6 primary + #f8fafc off-white) — Stripe, Linear, Notion auth convention.

Layout: lock icon badge (visual grounding for auth context), headline ("Reset your password"), sub-copy ("We'll send a reset link to your email"), email input with autocomplete='email', primary CTA ("Send reset link"), "Return to sign in" link, help microcopy at bottom ("Can't access this email? Contact support"). Total ~330px height — compact auth pattern, no scroll needed.

WCAG 2.1 dialog pattern: role='dialog' + aria-modal='true'. Focus starts on email input — users came here to type. Escape closes and returns to sign-in flow. Submit shows toast confirmation ("Check your email for a reset link") — pattern that reveals whether the email exists is a SECURITY ANTI-PATTERN (leaks account existence). Always show generic "If an account exists, we sent a link" message.

Make it yours

  • Add magic-link option below reset — "Or send me a sign-in link" bypasses password entirely. Notion, Slack, Vercel use this pattern for lower-friction auth.
  • Add rate-limit messaging ("Please wait 60 seconds before requesting another link") after first submit — prevents email flooding attacks on user accounts.
  • For SMS-based reset (mobile-first apps), replace email input with phone number + type='tel' + autocomplete='tel'.
  • Add "Contact support" chat widget (Intercom / Crisp) triggered from the help microcopy — recovers users blocked by lost email access.
  • For enterprise SSO, add "Sign in with SSO" option above email — bypasses password reset entirely for company-managed accounts.

Gotchas — read before shipping

  • NEVER reveal whether an email exists — showing "No account with this email" is a security anti-pattern (leaks account existence for enumeration attacks). ALWAYS show generic "If an account exists, we sent a link."
  • Rate-limit password reset requests — attackers use unlimited requests to flood victim inboxes. 5 requests per hour per IP is a reasonable cap.
  • Reset link tokens MUST expire (15-60 minutes standard) — long-lived reset tokens are a security risk if intercepted via compromised email.
  • Reset tokens MUST be single-use — after user clicks link and resets, the token must be invalidated. Multi-use tokens allow reset replay attacks.
  • Email autocomplete must be autocomplete='email' — otherwise password managers won't offer email autofill and mobile users get text keyboards instead of email-optimized keyboards.
  • For accessibility, the toast/confirmation message after submit must be in aria-live='polite' region — otherwise screen readers miss the confirmation and user doesn't know if reset was sent.
  • The 3deg rotate + subtle scale is intentionally UNDER-STATED — password reset users are already frustrated, dramatic overshoot bounces feel patronizing.
  • "Return to sign in" link should reopen the sign-in modal (Demo #02) if this reset flow was triggered from sign-in — don't just close and leave user on empty state.
