@otplib/preset-v11

Drop-in replacement adapter for migrating otplib from v11 to v13.

This adapter mimics the v11 API while using v13's plugins under the hood. However, some fundamental changes from v13 may carry over.

Note: This is intended as a temporary bridge to help you upgrade to v13 without rewriting your entire application immediately. We strongly recommend fully migrating to the new v13 API when possible.

Installation

npm install @otplib/preset-v11
pnpm add @otplib/preset-v11
yarn add @otplib/preset-v11

Usage

This package provides a drop-in replacement for otplib v11, using the v13 core.

import { authenticator, hotp, totp } from "@otplib/preset-v11";

const secret = authenticator.generateSecret();
const token = authenticator.generate(secret);
const isValid = authenticator.check(token, secret);

Compatibility Notes

• Epoch: Uses seconds (UNIX timestamp), same as v11.
• Error Handling: check and verify methods swallow errors and return false, matching v11 behavior.
• Secret Length: Enforces strict secret length (> 16 bytes) due to v13 core security requirements.

Migration Guide

For a full guide on migrating to v13 refer to the Migration Guide.
