It’s not a secret that nowadays a lot of people use mobile devices: smartphones, tablets, hybrids, you name it. Any device with a web browser can be used to login to your Facebook account; there’s a special version designed for this kind of devices, optimized for certain screen resolutions and designed with the mobile user in mind.
Using a traditional Web Browser
The easiest and simplest way to mobile login to Facebook is using a common web browser. Apple based products like iPhone, iPod or iPad have Safari, and Android based devices can use a wide range of mobile browsers like Firefox or Opera. Regardless of what browser you’re using, just visit the following URL:
http://m.facebook.com/
Immediately you will realize this is the mobile version of Facebook. The m in the URL indicates that you’re using a Mobile version and the Web UI (user interface) will change accordingly. Even if you visit that URL in your desktop computer, you’ll be able to see how Facebook would look like in your mobile browser window.

Using an official Facebook App
There are Facebook apps available for the most important mobile plattforms out there. For your security, never use an application that asks for your login details, unless it’s an official app. Currently, you can download, for free, any of these applications:
Once you’ve installed any of these apps, you’ll be required to login with your credentials. Just use your regular user/password combo and you’ll start enjoying Facebook in your mobile device. In regards to Facebook login, these articles could be useful to you:

Did you know that your Facebook account has 3 passwords?. It turns out that you can use different usernames to login; no matter which login name you want to use, you should be able to login successfully. These are the possible usernames you can use:
- Your e-mail address. This is the most common way to login.
- Your Profile Name (Vanity URL of your profile).
- Your Mobile number (only if you’ve associated it with your account).
Why too much usernames?
The reason for this is very simple: as Facebook was growing up, many users were using mobile devices to login to Facebook. This means that sometimes, it’s easier for the people to type their username or mobile phone instead of their e-mail address.

A lot of Facebook users have not linked their account with their mobile number yet. It’s considered a good practice to link your account and your number, for security reasons. It’s an extra layer of security to prevent unauthorized changes and/or hacking-related issues. If you’re phone number and you’re account are already linked, try to login to Facebook with your number.
Probably you didn’t know, but every single Facebook account out there, has 3 different passwords which you can use to login. The truth is that the other 2 passwords you didn’t know about, are in fact, variations of your original password and are generated automatically by Facebook by toggling uppercase and lowercase letters.
One password will be generated by toggling all uppercase and lowercase letters. The other password consist in toggling just the first letter of your current pass.

For example. Let’s assume that my Facebook password is My_custom_password!. That’s the regular secret word I use to login to my account, but as I explained before, there are two more variations of the same password. These would be my other passwords automagically generated by engineers and programmers at Facebook:
- Password 1: mY_CUSTOM_PASSWORD!
- Password 2: my_custom_password!
As you can tell, it’s not rocket science, and we don’t know what’s the purpose of this little trick. It does not represent any security flaw at all, and probably it was implemented as a test routine or something like that.
As a side note, remember that if you forget your password, you’d still need to reet it, regardless of the auto generated passwords we talked about before. Remember to update your security settings and never share your personal login credentials with anyone, unless you want your account to be compromised in the future.
