Frequently Asked Questions
How long should an OTP be?
6 digits is the most common standard (RFC 6238 TOTP). 4 digits suits low-security cases; 8 digits suits higher security applications.
Are these real TOTP codes?
No — these are pre-generated static codes, not time-based. Real TOTP requires a shared secret and timestamp. These are useful for bulk seeding test accounts or single-use verification.
