Most two-factor authentication systems provide backup codes, but if you need to generate your own reference codes or a supplementary set, this mode produces short alphanumeric codes designed to be written down and stored safely.
Create several passwords at once using the settings above — useful for provisioning multiple accounts.
Type any password to score it instantly. This runs entirely in your browser — nothing is sent anywhere, logged, or stored.
Most systems issue 8-10 backup codes at a time — use the bulk generator to create a matching batch.
Backup codes exist specifically for when you can't access your usual second factor — a printed copy in a safe place is genuinely useful here.
Backup codes are typically single-use — keep track of which ones you've already used to avoid confusion during a future recovery.
Not directly — this tool generates random codes in the same style for your own reference or supplementary use; always use the actual backup codes your specific service issues for real account recovery.
8-10 is typical, matching what most major services issue by default — use the bulk generator to create a matching set.
Somewhere offline and secure — a locked drawer or safe — separate from the device you'd normally use for two-factor authentication.
