A problem of this form of security is the tendency for consumers to forget their passwords. On average, an individual is registered to 25 online accounts requiring a password, and most individuals vary passwords for each account. According to a study by Mastercard and the University of Oxford, "about a third of online purchases are abandoned at checkout because consumers cannot remember their passwords." If the consumer does forget their password, they will usually have to request a password reset sent to their linked email account, further delaying the purchasing process. According to an article published by Phys Org, 18.75% of consumers abandon checkout due to password reset issues.
