Measured October 16, 2026 in a Chromium-based browser, by signing in to Bank of America and reading the sign-in cookie's expiry. This is what the browser was told; Bank of America's servers can still end a session sooner.
We retest every month. If Bank of America changes how long it remembers you, a new row shows up here.
