Login Blocks for Shadcn UI

A login page is a quiet promise: I’ll get you in fast. Every extra field, every misplaced error, every social button you don’t actually support is a tax on people who already trust you enough to come back.

Patterns

Login is the most-used page in any product. The pattern depends on how many ways users actually sign in—not how many ways you wish they used.

1. Centered card with email + password and one or two social providers
2. Split layout with marketing copy on one side and the form on the other
3. Magic link / OTP first, with password as a secondary option
4. Workspace selector for multi-tenant sign-in

Form rules

Login forms reward boring decisions. Native inputs, real labels, and proper autocomplete attributes outperform every custom widget on every metric that matters.

• One thing per line; no inline label/field hybrids
• Use type="email" and autocomplete="email", autocomplete="current-password"
• Show password reveal as an icon button with aria-pressed
• Inline validation only after blur, never on every keystroke

Errors

Error states are where login pages go wrong most often—either too vague to be useful or too specific to be safe. The right message lands in the middle.

• Be specific: "Email or password is incorrect" beats "Login failed"
• Place the error next to the field that caused it, not at the top of the form
• For rate limiting, show a quiet timer instead of a vague "try again later"
• Never reveal whether an email exists—phrase errors generically

Accessibility

Auth forms get used on every device, by every user, including people who depend on assistive tech every day. The defaults matter more here than almost anywhere.

• Associate every input with a <label>; placeholders are not labels
• Announce server errors via aria-live="polite"
• Maintain visible focus rings on inputs and submit buttons
• Make submit reachable on Enter from any field

Security

A login page is also a security surface. The form’s job is to authenticate; the markup’s job is to not leak anything that helps an attacker enumerate accounts.

• Always submit over HTTPS; reject form submissions otherwise
• Add a CSRF token if you’re not on a same-site cookie + POST flow
• Don’t bypass the password manager—use real form elements
• Throttle attempts on the server side and surface a clean message client-side
