Once you enable Facebook's two-factor authentication, which we strongly recommend, Facebook will ask you for a security or confirmation code to log in from a new location or device. Read our guide on two-factor authentication and why you should use it to learn more about this security method. Without two-factor authentication, you only need your username or email address and password to log into your Facebook account.
We went with the Text Message option and entered the six-digit code Facebook texted to our mobile number. You can use a phone number already associated with your account or add a new one. Once you've entered the Facebook confirmation code, click Finish to complete the initial setup.
Do you still have access to the mobile phone number you included under two-factor authentication Maybe your provider could send you a new SIM with the same number. In that case, let Facebook text you a confirmation code. Unfortunately, Facebook can only use that one number for two-factor authentication, even if you've set up other phone numbers under your profile.
You can also access the above recovery route through any browser, on desktop or mobile. Go to m.facebook.com and log into your account using your mobile number, email, or username and password. When prompted for the login code, click Having trouble > I don't have my phone > Continue.
The Facebook code generator is a security mechanism that assists in limiting unauthorized login to the account through an unknown device. A six-digit confirmation number must be entered each time you or anyone else uses your account from an unfamiliar device.
I've been using WhatsApp as well as my current phone number for at least eight years now. As of now, everything went pretty smooth. That's why the message four days ago, 13rd of August 2021, struck me: \"You've been banned from using WhatsApp\". I researched into the problem and contacted the WhatsApp support explaining that there shouldn't be any wrong-doings from my end. As a coincidence, I got a six-digit verification () code via SMS about an hour later (though I received a popup of someone else logging into my account beforehand).
Anyhow, two days pass and WhatsApp unbans me without a reason stating to why this happened. I moved on. Had to sign up on WhatsApp again (getting the \"normal\" verification message, i.e. a code including the normal message and not just six digit message). On top of my normal WhatsApp code, I now included my mail as a back-up 2FA mail.
... So comes yesterday evening. I get a pop-up stating someone tried logging into my account (+ a SMS message with only six digits). Went ahead with my day as there is nothing I could do except of not sharing the code. Today, 17th of August, I logged into my WhatsApp account and once again someone else \"logged into my account\". Upon trying to verify my number, I get a \"You've been banned from WhatsApp\" message. Here we go again: Contacting the WhatsApp support explaining myself.
When users log in to Twitter via a web browser, they must confirm their identity by entering a six-digit code that Twitter delivers to their smartphones. To access the service through applications for PCs and smartphones, users must use an automatically generated temporary password for each of the programs.
I have heard a story, which possibly may be apocryphal, that we are saddled with four-digit PINs because the engineer who originally invented the ATM asked his wife how long the card security codes should be, and she was quite unshakably certain that she could never POSSIBLY remember a number longer than four digits.
It was evident that something had gone wrong from the tweets the hacker sent from Honan's Twitter account and Gizmodo's account, to which it was linked. (He used to work there.) Honan went public on 3 August 2012 in a blogpost: Yes, I was hacked. Hard. At the time, he blamed his old seven-digit alphanumeric password.
With two-factor authentication, security depends on two different things. Often these are something you have, such as a credit card, and something you know, such as a four-digit pin (personal identification number). The \"something you have\" could also be a dongle or, with biometrics, your face, fingerprints, or iris patterns. With online services, it's usually a mobile phone. Set up two-factor authentication with Gmail, for example, and when you ask for your forgotten password to be reset, Google will send a verification code to your mobile.
--Some services such as Gmail even give you the option of using two passwords when you use a particular computer or device for the first time. If you have that feature turned on, the service will send a text message with a six-digit code to your phone when you try to use Gmail from an unrecognized device. You'll need to enter that for access, and then the code expires. It's optional, and it's a pain -- but it could save you from grief later on. Hackers won't be able to access the account without possessing your phone. Turn it on by going to the account's security settings. 1e1e36bf2d
