Some vendors have created separate installation packages for network login, Web access credentials and VPN connection credentials.
For such products, there may be four or five different software packages to push down to the client PC in order to make use of the token or smart card.
This translates to four or five packages on which version control has to be performed, and four or five packages to check for conflicts with business applications.
If access can be operated using web pages , it is possible to limit the overheads outlined above to a single application.
With other multi-factor authentication solutions, such as "virtual" tokens and some hardware token products, no software must be installed by end users.
There are drawbacks to multi-factor authentication that are keeping many approaches from becoming widespread. Some users have difficulty keeping track of a hardware token or USB plug.
Many users do not have the technical skills needed to install a client-side software certificate by themselves.
Generally, multi-factor solutions require additional investment for implementation and costs for maintenance. Most hardware token-based systems are proprietary and some vendors charge an annual fee per user.
Deployment of hardware tokens is logistically challenging. Hardware tokens may get damaged or lost and issuance of tokens in large industries such as banking or even within large enterprises needs to be managed.
In addition to deployment costs, multi-factor authentication often carries significant additional support costs. A survey  of over U. In their report, software certificates and software toolbar approaches were reported to have the highest support costs.
Research into deployments of multi-factor authentication schemes  has shown that one of the elements that tends to impact the adoption of such systems is the line of business of the organization that deploys the multi-factor authentication system.
Examples cited include the U. Despite the variations that exist among available systems that organizations may have to choose from, once a multi-factor authentication system is deployed within an organization, it tends to remain in place, as users invariably acclimate to the presence and use of the system and embrace it over time as a normalized element of their daily process of interaction with their relevant information system.
In , Kim Dotcom claimed to have invented two-factor authentication in a patent,  and briefly threatened to sue all the major web services.
Several popular web services employ multi-factor authentication, usually as an optional feature that is deactivated by default. From Wikipedia, the free encyclopedia.

This is also why it's important to use different passwords for all your accounts. This means that if you forget your password, you need two contact methods.
Or if you lose your contact method, your password alone won't get you back into your account—and it can take you 30 days to regain access.
You may even lose access to the account. When two-step verification is turned off, you will only have to verify your identity with security codes periodically, when there might be a risk to your account security.
Two-step verification begins with an email address we recommend two different email addresses, the one you normally use, and one as a backup just in case , a phone number, or an authenticator app.
When you sign in on a new device or from a new location, we'll send you a security code to enter on the sign-in page. For more info about the authenticator app, see How to use the Microsoft Authenticator app.
Go to the Security basics page and sign in with your Microsoft account. During sign-in, you can choose not to use 2-Step Verification again on that particular computer.
From then on, that computer will only ask for your password when you sign in. You'll still be covered , because when you or anyone else tries to sign in to your account from another computer , 2-Step Verification will be required.
See how it protects you. Most people only have one layer — their password — to protect their account.
With 2-Step Verification, if a bad guy hacks through your password layer, he'll still need your phone or Security Key to get into your account.
With 2-Step Verification, you'll protect your account with something you know your password and something you have your phone or Security Key.
Codes are uniquely crafted for your account when you need them. If you choose to use verification codes, they will be sent to your phone via text, voice call, or our mobile app.
Each code can only be used once.
