OTP (One-Time Password) signing
Two-factor authentication via SMS or email — fast, from any browser, no extra device required.
For workflows where speed and accessibility matter most, Doxera offers signing with a one-time code sent via SMS or email. Ideal for occasional external signers (clients, partners) without a qualified signature setup.
