OTP Login

Provides a one-time passcode login flow where users receive a short code by email and type it into the site to log in, instead of using password or “magic link” logins.

Features

• Request a numeric login code at /user/login.
• Verify the code at /user/login/verify to sign in without a password.
• Configurable code length and expiration at admin/config/people/otp.
• Password-based login and password reset pages are disabled/redirected.

Installation

1. Place this module in modules/contrib/otp and enable it.
2. Visit admin/config/people/otp to adjust code length or expiration.

Usage

• Anonymous users visit /user/login, enter their account e-mail, and receive a code via e-mail.
• They enter the code at /user/login/verify to complete login.
• Destination parameters are preserved when present and not external.
