One-Time Password (OTP) Verification
A method of verifying a signer's identity by sending a temporary code to their email address. The signer must enter the code to proceed with signing.
OTP verification provides a balance between security and convenience. It proves that the person signing has access to the email address they claim to own.
In Signbee, OTP verification is used when the sender does not have an API key. A 6-digit code is sent to their email, and they enter it to verify their identity before the signing link is sent to the recipient.
