OTV Code Generator

What is One-Time Verification (OTV) Code Generator

OTV code generator is a hardware device used to generate a one-time verification code. This code is part of the two-factor authentication system, used as an additional security measure when signing in to Ryerson web applications via Ryerson’s Central Authentication Service (CAS).

Who Can Use OTV Code Generator

At present, all faculty and staff at Ryerson University can use the OTV code generator. Even though it is primarily made available for the convenience of users without the supported mobile devices, it can be used by all users to get the Ryerson Authentication code conveniently.

How to Get OTV Code Generator

  1. Go to CCS Forms web site and select Request for One-Time Verification (OTV) Code Generator.

  2. Fill out the form. The request must be approved by your Director, Chair or Dean. An OTV code generator is provided by a third party company and there is a $30 charge for it.

  3. Once the request is approved, you will be informed by email to come to pick up the OTV code generator from CCS Reception, located in room LIB-B99. The hours of operation are from 8:30am-4:30pm (Monday - Friday).

  4. The OTV code generator will be assigned to your my.ryerson account. Each code generator comes with a unique identifier that has to be assigned to its owner’s account.

What to do in Case You Lose Your OTV Code Generator

As soon as you realize that you have lost the OTV code generator, you will need to get your Two-Factor authentication revoked for this device. You will be able to do it yourself if you can login to my.ryerson portal without using OTV code (you registered your OTV code for 'all applications' as in step 6 under section 'How to Activate and Use OTV Code Generator'). If not, ask CCS Help Desk at ext. 6806 or at at your earliest convenience.
