The basic steps to sign in to Facebook
To log into Facebook, go to facebook.com on a computer or open the Facebook app on your phone, enter the email address or phone number linked to your account, type your password, and click or tap the login button. If you have two-factor authentication turned on, you will also need to enter a security code sent to your phone or generated by an authenticator app.
The process is the same whether you are using a desktop browser, a mobile browser, or the official Facebook app. Facebook remembers your login on devices you use regularly, so you may not need to enter your password every time.
Key Takeaways
- You can log in using either the email address or phone number you registered with, plus your password.
- If you have two-factor authentication enabled, you will need a security code from your phone or authenticator app in addition to your password.
- Facebook can save your login on devices you trust, so you do not have to enter your password every time you visit.
- If you cannot remember your password, use the "Forgot Password" link on the login page to reset it through your email or phone number.
Logging in on a computer or laptop
Open any web browser and go to facebook.com. You will see the login form on the left side of the page. Enter the email address or phone number associated with your Facebook account in the first field, then enter your password in the second field. Click the blue "Log In" button.
If you see a checkbox that says "Keep me logged in," checking it will save your login on that computer. This means you will not have to enter your password the next time you visit Facebook from that device. Only use this option on computers you own or trust — do not check it on shared or public computers.
Logging in on your phone or tablet
Open the Facebook app or go to facebook.com in your phone's browser. The login form will appear on your screen. Enter your email address or phone number, then your password, and tap the login button. The process is identical whether you use the app or the mobile website.
On phones, Facebook typically remembers your login unless you manually sign out. If you share your phone with others, you can sign out after each use by tapping the menu icon (three horizontal lines), scrolling down, and selecting "Log Out."
What to do if you do not remember your password
On the Facebook login page, click or tap "Forgot Password?" below the login button. Facebook will ask you to enter the email address or phone number linked to your account. Enter it and click "Search."
Facebook will show you account recovery options. You can receive a password reset link by email or text message. Click the option that works for you, follow the link or code you receive, create a new password, and log in with it. Make sure your new password is something you can remember or store securely.
Understanding two-factor authentication during login
If you have turned on two-factor authentication in your Facebook settings, the login process includes an extra step. After you enter your password, Facebook will ask for a security code. This code is either sent to your phone as a text message or generated by an authenticator app like Google Authenticator or Microsoft Authenticator.
Enter the code in the field Facebook provides. The code is valid for a short time — usually a few minutes — so enter it quickly. If the code expires, you can request a new one. Two-factor authentication makes your account much harder to break into, even if someone learns your password.
Staying secure while logging in
Always log in through facebook.com or the official Facebook app from the App Store or Google Play. Fake login pages exist on the internet designed to steal passwords. Check that the web address in your browser starts with "https://" and shows "facebook.com" — not a similar-looking address.
Never share your password with anyone, including Facebook staff or friends. Facebook employees will never ask for your password. If someone claims to be from Facebook and asks for it, that is a scam. Use a unique password for Facebook that you do not use on other websites, so if one site is breached, your Facebook account stays protected.
What to do if you cannot log in
If you enter your password and see an error message, first check that you are typing it correctly. Passwords are case-sensitive, meaning capital letters matter. If you are still stuck, use the "Forgot Password?" option to reset it.
If you see a message saying your account is locked or disabled, Facebook may have detected unusual activity or a violation of its rules. Visit facebook.com/login/identify to follow Facebook's account recovery process. You may need to confirm your identity by uploading a photo of your ID or answering security questions you set up earlier.
Frequently Asked Questions
Can I log in with my username instead of my email or phone number?
No, Facebook requires either the email address or phone number linked to your account. If you do not remember which email you used, try the phone number instead, or use the "Forgot Password?" option to recover your account.
Why does Facebook keep logging me out?
Facebook may log you out if you clear your browser cookies, if your password was recently changed, or if Facebook detected suspicious activity on your account. If this happens repeatedly, change your password and check your login activity in Facebook settings to see if someone else is accessing your account.
Is it safe to use "Keep me logged in" on my phone?
Yes, if it is your personal phone that only you use. If you share your phone with family members or roommates, do not check this option, and sign out after each use instead.
What if I see a login code request I did not make?
This means someone tried to log into your account. Do not share the code with anyone. Change your password immediately and review your login activity in Facebook settings. If you see logins from places you do not recognize, sign out all other sessions.
Can I log in to multiple Facebook accounts on the same device?
Yes. Log out of the first account, then log in with the second account's email or phone number and password. Facebook will remember both logins on that device, and you can switch between them using the account menu.
