Security Badges Login Block for React

Nothing leaves the page. The four safeguards are typed in SAFEGUARDS for a fictional product, and so are their cards. Sign-in waits under a spinner for less than a second, then shows "You're signed in" and a polite status message says nothing was sent. Replace each entry with a fact your product really keeps, and write where it stops as carefully as what it does; post the form to your auth endpoint where the code says so.

A badge claims a certification you have to hold and keep, and a bare "256-bit" or "99.9% uptime" can't be checked from a sign-in page. A fact such as "sessions end after 30 days idle" is something your product either does or doesn't, and the card beside it says what it doesn't cover. If you do hold an audit, link its report from a card instead of drawing a seal.

Each cell is a real button. Hover opens its card; so does keyboard focus, and Escape closes it. A small piece of state in the block opens the card on focus and on a tap (a press on a screen with no hover) and closes it on blur or Escape. The card's text is also tied to the button as its description, so a screen reader hears what it says without opening it.

The four cells go two across and two down, each keeping its icon, name and a line of words, and the strip sits below the Sign in button, so the button stays on the first screen. The cards are narrower than the screen and open above the cell when there is room, below it when there isn't.

It's what makes the claim credible: a password that is hashed doesn't protect one you reuse, an email alert doesn't block a sign-in, and a breach list is only as new as the last release. A visitor who reads the limits trusts the rest more, and your support team gets fewer surprises.

A disabled button can't explain itself, and keyboard users can't reach it. Pressing Sign in with an empty or malformed email, or no master password, marks those fields invalid, writes one sentence under each and moves focus to the first. Typing clears that field's problem, and each field keeps a line for its problem even when there is none.
