Abstract
The present teaching relates to adjustable one-time password (OTP) setup, sign-in, and verification. In one example, a first length of a signature is determined. The signature has been used previously by a first user to initially sign in a second device. A second length that is different from the first length is determined. A signing key is generated based at least partially on the second length. A new signature having the second length is generated based on the signing key. The new signature is provided to a second user so that the second user can input at least a portion of the new signature into the second device for a subsequent sign in. The verification key is generated based at least partially on the new signature. The new signature input by the second user into the second device is transmitted from the second device to the third device.
