Duo tokens/fobs do not need to be returned to the University or the DoIT Help Desk. They should be disposed of following electronic recycling guidelines: https://dnr.wisconsin.gov/topic/Ecycle/Electronics.html. 

• Tokens and Fobs will automatically be de-registered from a user in our database once access to Duo is removed. 
• Due to battery limitations, tokens and fobs will not be reused. 
• Tokens and Fobs can be returned to the Help Desk to be recycled. Once returned to the Help Desk for recycling, we can not retrieve the old token (ex: a token is given to the Help Desk for recycling but then the customer realizes they still need it) - however, we can issue a new one.
