The “save login info” setting on Facebook allows users to store their login credentials, so they don’t have to enter their username and password every time they want to access Facebook. When this setting is enabled, Facebook will remember the user’s login information and automatically log them in when they visit the Facebook website or mobile app.
Should you use the save login info setting?
There are advantages and disadvantages to using the “save login info” setting on Facebook:
Advantages of saving login info
- Convenience – Don’t have to enter username/password every time
- Time savings – Faster to log in, especially on mobile
- Avoid typos – Don’t have to worry about inaccurately typing login credentials
Disadvantages of saving login info
- Security risk – If device is lost/stolen, account can be accessed
- Shared devices – Anyone with device access can log in to your account
- Forget to log out – Can leave you logged in on public computers
Ultimately it’s a personal decision whether the convenience outweighs the minor security risks. Some recommendations:
- Only save login on personal devices
- Use strong unique passwords
- Enable 2-factor authentication
- Log out fully after each use on shared devices
How to enable/disable saving login info
Saving login info is enabled by default on Facebook. To change this setting:
On Desktop
- Click the down arrow in the top right
- Select “Settings & Privacy”
- Click “Settings”
- Click “Security and Login”
- Under “Where You’re Logged In”, toggle “Save Browser Logins” on or off
On Mobile App
- Tap the hamburger menu icon (3 lines)
- Scroll down and tap “Settings & Privacy”
- Tap “Settings”
- Tap “Security and Login”
- Toggle “Save Logins” on or off
Once changed, the new setting takes effect immediately. Existing saved login credentials will be cleared if you disable the setting.
How Facebook login saving works
When you first log into Facebook from a browser or app, you’ll be prompted to save your login credentials. If you accept, Facebook stores an encrypted copy of your username and password on that device.
The next time you visit, Facebook will automatically populate the login fields and log you in after a quick verification. You won’t have to manually enter anything.
Facebook uses secure browser data storage APIs to save your credentials. For example:
- Chrome – Credentials API
- Safari – Keychain
- iOS – Keychain
- Android – Account Manager
Your login credentials are stored locally on your device only. They are not sent to or stored by Facebook’s servers.
Is saving Facebook login info secure?
Saving login credentials is generally considered reasonably secure, with a few caveats:
- Anyone with physical access to the device can log in. Enable device lock screens.
- Malware on a device could collect saved credentials. Keep devices clean.
- Credentials could sync to new devices via backup. Understand sync risks.
However, the stored credentials are securely encrypted using industry standards like AES-256 or PBKDF2. The device data storage APIs used are also designed specifically for sensitive information like passwords.
So while not completely risk-free, saving Facebook login credentials is relatively safe if device security precautions are taken.
How to check where you’re logged into Facebook
To see all the devices and browsers where your Facebook account is currently logged in:
- Click the down arrow in the top right
- Select “Settings & Privacy”
- Click “Settings”
- Click “Security and Login”
- Scroll down to “Where You’re Logged In”
This shows all active Facebook sessions across devices. You can log out of any individual sessions here.
It’s a good idea to periodically check where you’re logged in and log out of any unknown or unwanted sessions. This prevents unauthorized access if a device is lost, stolen, or shared.
How to log out of Facebook on all devices
If you want to fully log out of Facebook across all devices and browsers, here are your options:
Log Out of All Sessions
- Click down arrow in top right
- Select “Settings & Privacy”
- Click “Settings”
- Click “Security and Login”
- Scroll down and click “Log Out Of All Sessions”
This immediately ends all active Facebook sessions logged into your account across all devices.
Change Your Password
- Click down arrow in top right
- Select “Settings & Privacy”
- Click “Settings”
- Click “Security and Login” > “Change Password”
Changing your Facebook password logs you out of all active sessions. Anyone trying to access your account will need the new password.
Deactivate Account
Deactivating your Facebook account also logs you out automatically everywhere. However, deactivation is meant for extended breaks from Facebook, not general log outs.
Conclusion
Saving login information makes frequent Facebook access more convenient by avoiding constant re-entry of credentials. But it also carries minor security risks if devices are not properly safeguarded.
Enabling the “Save Login” option is recommended only for personal devices that you control. Use strong unique passwords and two-factor authentication for improved security.
Check your active sessions periodically and fully log out of Facebook before accessing untrusted computers. Overall, the login saving feature provides helpful convenience with limited risks for most users.
