2 Step Authentication Play Fortnite Battle Royale on the go! Same gameplay, same map, same weekly updates. VideoHere's how hackers can get around 2-factor authentication
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.
Under Two-step verification , choose Set up two-step verification to turn it on, or choose Turn off two-step verification to turn it off. Depending on what security info you have added to your account, this requirement might mean entering a security code from your authenticator app and entering a security code that was emailed to your backup email account.
Instead of receiving one security code to verify your identity, though, you'll receive two. Some apps like the mail apps on some phones or devices like the Xbox can't use regular security codes.
App passwords are only available if you use two-step verification. If you don't have two-step verification turned on, you won't see the App passwords section on the Additional security options page.
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. See Features to learn about backup options for times when your phone is not available. Two-factor authentication also known as 2FA is a type, or subset, of multi-factor authentication.
It is a method of confirming users' claimed identities by using a combination of two different factors: 1 something they know, 2 something they have, or 3 something they are.
A third-party authenticator TPA app enables two-factor authentication, usually by showing a randomly-generated and constantly refreshing code which the user can use.
Two-step verification or two-step authentication is a method of confirming a user's claimed identity by using something they know password and a second factor other than something they have or something they are.
Authentication takes place when someone tries to log into a computer resource such as a network, device, or application. The resource requires the user to supply the identity by which the user is known to the resource, along with evidence of the authenticity of the user's claim to that identity.
Simple authentication requires only one such piece of evidence factor , typically a password. For additional security, the resource may require more than one factor—multi-factor authentication, or two-factor authentication in cases where exactly two pieces of evidence are to be supplied.
The use of multiple authentication factors to prove one's identity is based on the premise that an unauthorized actor is unlikely to be able to supply the factors required for access.
If, in an authentication attempt, at least one of the components is missing or supplied incorrectly, the user's identity is not established with sufficient certainty and access to the asset e.
The authentication factors of a multi-factor authentication scheme may include: [ citation needed ]. A good example of two-factor authentication is the withdrawing of money from an ATM ; only the correct combination of a bank card something the user possesses and a PIN something the user knows allows the transaction to be carried out.
Two other examples are to supplement a user-controlled password with a one-time password OTP or code generated or received by an authenticator e.
A third-party authenticator app enables two-factor authentication in a different way, usually by showing a randomly-generated and constantly refreshing code which the user can use, rather than sending an SMS or using another method.
A big benefit of these apps is that they usually continue to work even without an internet connection. Examples of third-party authenticator apps include Google Authenticator , Authy and Microsoft Authenticator ; some password managers such as LastPass offer the service as well.
An example of a second step in two-step verification or authentication is the user repeating back something that was sent to them through an out-of-band mechanism such as a code sent over SMS , or a number generated by an app that is common to the user and the authentication system.
Knowledge factors are the most commonly used form of authentication. In this form, the user is required to prove knowledge of a secret in order to authenticate.
A password is a secret word or string of characters that is used for user authentication. This is the most commonly used mechanism of authentication.
Many multi-factor authentication techniques rely on password as one factor of authentication. Variations include both longer ones formed from multiple words a passphrase and the shorter, purely numeric, personal identification number PIN commonly used for ATM access.
Traditionally, passwords are expected to be memorized. Many secret questions such as "Where were you born?
Possession factors "something only the user has" have been used for authentication for centuries, in the form of a key to a lock.
The basic principle is that the key embodies a secret which is shared between the lock and the key, and the same principle underlies possession factor authentication in computer systems.
A security token is an example of a possession factor. Disconnected tokens have no connections to the client computer.
They typically use a built-in screen to display the generated authentication data, which is manually typed in by the user.
This type of token mostly use a "one-time password" that can only be used for that specific session. Connected tokens are devices that are physically connected to the computer to be used.
Those devices transmit data automatically. A software token a. Software tokens are stored on a general-purpose electronic device such as a desktop computer , laptop , PDA , or mobile phone and can be duplicated.
Contrast hardware tokens , where the credentials are stored on a dedicated hardware device and therefore cannot be duplicated, absent physical invasion of the device.
A soft token may not be a device the user interacts with. Typically an X. These are factors associated with the user, and are usually biometric methods, including fingerprint , face , voice , or iris recognition.
Behavioral biometrics such as keystroke dynamics can also be used. Increasingly, a fourth factor is coming into play involving the physical location of the user.
While hard wired to the corporate network, a user could be allowed to login using only a pin code while off the network entering a code from a soft token as well could be required.
This could be seen as an acceptable standard where access into the office is controlled. Systems for network admission control work in similar ways where your level of network access can be contingent on the specific network your device is connected to, such as wifi vs wired connectivity.
This also allows a user to move between offices and dynamically receive the same level of network access in each.
Many multi-factor authentication vendors offer mobile phone-based authentication. Some methods include push-based authentication, QR code based authentication, one-time password authentication event-based and time-based , and SMS-based verification.
SMS-based verification suffers from some security concerns. Phones can be cloned, apps can run on several phones and cell-phone maintenance personnel can read SMS texts.
Not least, cell phones can be compromised in general, meaning the phone is no longer something only the user has. The major drawback of authentication including something the user possesses is that the user must carry around the physical token the USB stick, the bank card, the key or similar , practically at all times.
Loss and theft are risks. Many organizations forbid carrying USB and electronic devices in or out of premises owing to malware and data theft-risks, and most important machines do not have USB ports for the same reason.
Physical tokens usually do not scale, typically requiring a new token for each new account and system. Procuring and subsequently replacing tokens of this kind involves costs.Die Multi-Faktor-Authentifizierung, auch Multifaktor-Authentisierung, ist eine Verallgemeinerung der Zwei-Faktor-Authentisierung, bei der die Zugangsberechtigung durch mehrere unabhängige Merkmale überprüft wird.

Depending on what security info you have 1001 Denkspiele to your account, this requirement might mean entering a security code from your authenticator app and entering a security code that was Hulk Spiele Kostenlos to your backup email account. Passwords can be compromised if you use the same password for multiple accounts, click on malicious links, open phishing emails and other methods. If your password is compromised and becomes known to someone other than yourself, your account will still require a verification code to gain access when you activate 2-Step Verification. 2-Step Verification can help keep bad guys out, even if they have your password. Imagine losing access to your account and everything in it When a bad guy steals your password, they could lock you. Two-step authentication involving mobile phones and smartphones provides an alternative to dedicated physical devices. To authenticate, people can use their personal access codes to the device (i.e. something that only the individual user knows) plus a one-time-valid, dynamic passcode, typically consisting of 4 to 6 digits. To enable Two-Step Verification: Go to Advanced Security Settings. Click Get Started to set-up Two-Step Verification. Add your primary phone number (this phone must be able to receive SMS messages) or download and configure an authenticator app and click Send code. To opt into Two-Factor Authentication: In your ACCOUNT Settings, click on the PASSWORD & SECURITY tab to view your security settings.
