Facebook Login: Complete Guide to Sign In
Everything you need to log in to Facebook — on desktop, mobile app, or browser — plus how to fix login errors, recover a hacked or disabled account, set up two-factor authentication, and stop unexpected logouts.
To log in to Facebook, go to facebook.com (or open the Facebook app), enter the email, phone number, or username linked to your account, then enter your password and tap Log In. If two-factor authentication is enabled, you'll also confirm a code sent via SMS or your authenticator app.
Understanding Your Facebook / Meta Account
Facebook accounts are part of the broader Meta account system, which also covers Instagram, Messenger, and Meta's other apps. Depending on how your account is set up, you may notice:
- Messenger
- Instagram (if linked)
- Meta Business Suite
- Meta Horizon (VR)
- WhatsApp Business (separate login)
Logging in once on a device often keeps you signed in across Facebook and Messenger automatically, since they share the same underlying account system on most devices.

Facebook Login With Email vs. Phone Number
Depending on how your account was created, you can typically log in with any of the following:
| Identifier | How It Works | Notes |
|---|---|---|
| Email address | Any email linked to your account, including secondary emails | Most common login method |
| Phone number | Must be the exact number linked during signup or added later | Common for accounts created via mobile |
| Username | Custom Facebook username if you've set one (facebook.com/yourname) | Less common, but still valid for login |
If none of these work, you may be using the wrong identifier — try "Forgotten password?" and search by name, email, or phone to find the linked account.
Setting Up Two-Factor Authentication for Facebook
Two-factor authentication (2FA) adds a second verification step beyond your password, making it significantly harder for someone else to access your account even if they know your password.
How to Enable 2FA
- Go to Settings & Privacy → SettingsFrom the menu in the Facebook app or website.
- Select "Password and Security"This section manages all login security options.
- Tap "Two-Factor Authentication"Then select "Use two-factor authentication."
- Choose your methodAuthentication app (recommended), text message (SMS), or security key.
- Follow the setup steps for your chosen methodScan a QR code for an authenticator app, or confirm your phone number for SMS.
- Save your recovery codesStore these somewhere safe in case you lose access to your 2FA method.
Logging In via Google or Apple (Linked Accounts)
If you previously linked your Facebook account to a Google or Apple sign-in option (sometimes available on mobile devices), you can use that same method to log in faster — no password needed, just your device's biometric or PIN confirmation.
If you're unsure whether you set this up, try the standard email/password login first. If that fails and you recall seeing "Continue with Apple" or "Continue with Google" during signup, look for those options on the login screen.

Frequently Asked Questions
Why can't I log into Facebook even with the correct password?
This is often caused by using the wrong login identifier (email vs phone vs username), a browser cache issue, or a temporary account restriction. Try "Forgotten password?" to confirm which identifier is linked to your account, and clear your browser cache before retrying.
How do I recover my Facebook account if I lost access to my email and phone?
Use Facebook's "Find Your Account" tool and search by name. If you can identify the account but can't receive a code, look for the option to verify your identity using trusted contacts or government ID upload, depending on what's available for your account.
Can I create a Facebook account without giving my real name?
Facebook's terms require using the name you go by in everyday life, and accounts using clearly fake names can be flagged or restricted. However, Facebook does allow some flexibility for nicknames and name variations that people commonly use.
Is Facebook Lite different from regular Facebook login?
Facebook Lite uses the same login credentials as the regular Facebook app — it's a smaller, data-efficient version designed for slower connections and older devices. You can use the same email/phone and password on both.
How long does Facebook account recovery take?
If you have access to your linked email or phone, recovery can take just minutes. If you need identity verification (e.g., uploading ID), review can take anywhere from 24 hours to several days depending on volume.
What's the minimum age to create a Facebook account?
Facebook requires users to be at least 13 years old (or the minimum age in their country, which may be higher) to create an account, in line with global data protection regulations.
Can I have two Facebook accounts with one phone number?
Facebook generally limits how many accounts can be linked to a single phone number for security reasons. While it's technically possible in some cases, Facebook's policies favor one account per person, and maintaining multiple personal accounts can risk both being flagged.
Why does Facebook keep logging me out?
This is usually caused by browser settings that clear cookies automatically, the "Save Browser" option not being selected, or multiple devices triggering frequent security re-checks. See our dedicated guide for full troubleshooting steps.
