Password for
Wise
Wise (formerly TransferWise) requires a minimum of 8 characters and accepts uppercase, lowercase, numbers and symbols, but for an account that holds balances in multiple currencies and sends international transfers, an 8-character password is far too weak against offline cracking and credential-stuffing. The practical recommendation in 2026 is a 16-character random string across the full character set, which delivers roughly 104.9 bits of entropy. At that strength the number of possible combinations is astronomically large — far longer than the universe has existed to brute-force — making the password effectively uncrackable. Generate one below: it is created inside your browser using the Web Crypto API and is never transmitted to a server or stored anywhere. Pair it with app-based two-factor authentication — an authenticator app rather than SMS — so that a leaked password on its own cannot reach your funds.

Wise password rules
Financial accounts are high-value targets. Use a unique password here and enable every available security layer (2FA, login alerts, etc.).
The distance between Wise's minimum and a robust password is large. An 8-character full-keyset password carries about 52.4 bits of entropy, below the 80-bit level NIST SP 800-63B recommends for high-value accounts. A 16-character random string lifts that to roughly 104.9 bits. The improvement is exponential rather than additive — each added random character multiplies the search space an attacker faces. Where 52.4 bits is tractable for GPU clusters working against a leaked hash, 104.9 bits is computationally unreachable by any foreseeable hardware. For an account that holds money and moves it across borders, satisfying the NIST 80-bit guideline is the floor, and 104.9 bits exceeds it comfortably.
Why Wise accounts are targeted
Money-transfer accounts like Wise are targeted for direct monetary loss: an intruder who gains access can drain currency balances or push funds out as international transfers, which are fast and hard to recall once sent. The most common account-takeover routes are credential stuffing — replaying passwords leaked in unrelated breaches — and phishing that harvests login credentials directly, sometimes paired with SIM-swap attempts to intercept SMS codes. These methods exploit the user rather than the platform itself, making a strong individual defence the decisive factor. A long, unique password generated locally in your browser, combined with app-based two-factor authentication, closes off the cheapest and most frequently used routes to your balance.
