We signed into real sites and read the cookie each one set. The box rarely mattered. Most sites didn't offer one.
| Site | The box | Checked | Unchecked | Finding | Tested |
|---|---|---|---|---|---|
| Steam | Remember me, pre-checked | 400 days | 400 days | No difference. Both hit Chrome's 400-day cap on the same day. | Oct 2026 |
| Bank of America | None. "Save user ID" only | n/a | session only | Signed out about 10 minutes after sign-in. Your card-view preference is kept for 400 days. | Oct 2026 |
| GitHub | None | n/a | 14 days | The cookie that says you're logged in lasts 365 days. The session lasts 14. | Oct 2026 |
| Amazon | Never shown | n/a | 365 days | Passkey sign-in skipped the page with the box. Signed in for a year without being asked. | Oct 2026 |
