You can only create a personal profile under your own name on Facebook, but you may make pages for your pen names. Though some people manage to avoid detection by adopting a pen name for their real page, Facebook will terminate your account if they discover it. Thus, it is not recommended that you use a pen name.
You can only log in to Twitter with your real name. However, we do allow users to set up custom profiles for themselves or others. These profiles cannot be changed without the original owner's permission and if someone else uses your custom profile, they will see only your first name before theirs.
You can only log in to Instagram with your full legal name.
Google+ was previously called "Google Plus", so certainly yes! You can use any nickname or alias you want for Google+. Just like other social networks, you can connect using your actual name or a pseudonym.
If you wish to use a pseudonym because it's a stage or professional name, Facebook already provides alternative possibilities. They advise you to create a Facebook profile using your genuine account. You may then ask all of your friends to like the page and use it to manage anything relating to your other identity. This process is called "fanning" and it's free.
If you want to do this without revealing your true identity, you can make an anonymous Facebook account by simply logging into Facebook with a non-personal email address. It's recommended that you use a free service such as Gmail or Yahoo! to control access to your email from different devices. You can also make use of a unique password for your anonymous account. As long as you don't share your real name or contact information with anyone, you should be able to keep your secret identity hidden for as long as you need to.
The ability to create an alias online allows you to play games under a different name without having to provide any personal details about yourself. It also opens up opportunities to connect with people all over the world and form new friendships. If you have ever wanted to join a gaming clan or participate in other interactive forums under a different identity, this is now possible using just your Facebook account.
Facebook has always required users to use their true identities when registering on the platform. Using a pseudonym online does not violate any laws (at least not in the United States), but being detected using a false identity might result in your profile being blocked or removed. This is the risk you take until Facebook changes its policy.
Facebook asks users to "give the name they use in real life" so that others may identify with whom they are connected. "This contributes to the safety of our neighborhood," the business adds. Users can change their names at any time by logging into Facebook, clicking on the Settings button, then selecting the User Options screen.
Facebook has long maintained a "real name" policy, which states that your profile name must be "the name [you] go by in everyday life." Obviously, you can enter a fictitious name and get away with it for a time. But that's not permitted, and it may get you in trouble.
There are several ways you can change your Facebook name without having to provide an actual first or last name. You can use any name you want as long as it isn't discriminatory, hateful, threatening, or pornographic. It also helps if the name isn't already taken by someone else. If you choose to use a pseudonym, however, then you'll need to provide a real identity behind it.
You can use a made-up name for your Facebook profile name, but you must give some thought as to whether this is something you should be doing. After all, people need to know how to reach you! If you don't want to tell the world your real name, then use a made-up one instead. However, it's recommended that you at least include your first and last names in your profile so that it's possible to find you in case you want to be contacted in an emergency.
It is advisable to use a made-up name for your Facebook profile if you don't want anyone to contact you there.
Users are not authorized to use false identities on their Facebook profiles. Use your full name at all times. Only if you officially change your name, such as when you marry, may you change it after your account is created. Intentionally impersonating another person on Facebook is a particularly egregious breach of Facebook regulations. Users found to have done so will be subject to disciplinary action including but not limited to the removal of access to their account.
Although Facebook reportedly requires each user to disclose his or her genuine name—something many people avoid—certain characters, punctuation marks, and objectionable language will not pass inspection anyway. Thus, one's true identity is largely irrelevant to the service.
In fact, there are several examples of famous people who use fake profiles or multiple identities. The site has been used by some members to create false profiles for fraudulent purposes, such as engaging in spam or other types of online scams.
Furthermore, some users may choose to use a pseudonym or alias when using the site. For example, some people may want to post information about themselves that isn't private, such as their current job status or public photos of themselves with friends.
Users can also make new profiles in the names of other people if they do not have their own account yet. This is called "sock puppet" behavior and is common among young users who might not have access to their parents' credit cards or email addresses. These users often create dozens of different profiles under various names (including images) to see what kinds of information they can post without being detected.
Finally, some people may want to use a false identity for privacy reasons. Some people may not want their employers, classmates, or family members to see their full name when it appears on Facebook.
