Mga Madalas Itanong

Gaano katagal dapat ang isang OTP?

Ang 6 na digit ang pinaka-karaniwang pamantayan (RFC 6238 TOTP). Ang 4 na digit ay angkop para sa mga kaso ng mababang seguridad; ang 8 na digit para sa mga aplikasyon na may mas mataas na seguridad.

Mga tunay bang TOTP code ang mga ito?

Hindi — ito ay mga pre-generated na static na code, hindi nakabatay sa oras. Ang tunay na TOTP ay nangangailangan ng shared secret at timestamp. Kapaki-pakinabang ang mga ito para sa bulk seeding ng mga test account o single-use verification.
