Safe & secure

How your money is protected.

Rein is built to be trusted with the thing that matters most. Here's exactly how your money is held, how your account is locked down, and what a decline really means — stated plainly, not buried in fine print.

Your funds

Held as a secured deposit. Not lent out.

Your balance sits as a secured deposit at our partner bank, a Member FDICinstitution. It isn't invested, isn't lent out, and isn't put at risk — it's collateral that doubles as the spending limit on your secured charge card.

FDIC insurance covers the failure of an FDIC-insured bank, up to applicable limits and subject to certain conditions being met. Rein is a financial technology company, not a bank.

Account protection

Locked down by default.

Modern security you don't have to think about — with controls right in your hand when you need them.

Face ID & passkeys

Biometric unlock and phishing-resistant passkeys guard access to your account and card details.

Instant freeze

Freeze any card in a single tap. Nothing moves until you unfreeze it — no phone call required.

Real-time alerts

A notification on every transaction, with the envelope and remaining balance, so nothing is a surprise.

Merchant-locked cards

Online purchases can use a virtual card locked to one merchant, so a leak can’t be reused elsewhere.

Encrypted end to end

Card details are revealed through a secure, tokenized flow — never stored in plain sight.

Disputes, built in

File a dispute from the transaction itself and track it to resolution inside the app.

A different kind of decline

On Rein, a declined swipe is your own rule firing — never a lack of funds, never an overdraft, never insolvency. It means the plan worked. Covering it takes one tap.

Money you can trust to hold the line.
