What does "log in" mean?

To log in means to enter your username, email, or password to get access to a website, app, or computer system. You do this every time you open something like your email, a streaming service, or an online bank account. It is a very common action in everyday digital life, and you will see the instruction 'Please log in' on many websites. The phrasal verb is the same in both British and American English, and it works in all situations — from chatting with friends to reading official instructions.

Common Mistakes

Writing 'login' as a verb

'Login' (one word) is a noun or adjective, not a verb. For example, 'your login details' is correct, but you must write the verb as two separate words: 'log in'.

Please login to continue.
Please log in to continue.
Wrong preposition after 'log in'

When you name the system or account you are accessing, always use 'to', not 'in' again or no preposition at all.

Log in your account to check your messages.
Log in to your account to check your messages.
Confusing 'log in' with 'sign up'

'Log in' is what you do when you already have an account and want to access it. 'Sign up' is what you do to create a new account for the first time.

I don't have an account yet, so I'll log in.
I don't have an account yet, so I'll sign up.

Usage

This phrasal verb is neutral and works in all situations, from casual chat to technical instructions. It is equally common in British and American English, and interchangeable with 'sign in' in most contexts.

Frequently Asked Questions

Is 'log in' the same as 'sign in'?

Yes, they mean exactly the same thing in everyday use — both describe entering your credentials to access an account or system. Different platforms choose different words: Google and Microsoft often say 'sign in', while many other websites say 'log in'. You can use them interchangeably in conversation.

What is the difference between 'log in' and 'log on'?

'Log in' and 'log on' are very similar, but 'log in' is the more modern and common form, especially for websites and apps. 'Log on' is still used, but you will hear it more in older or more technical contexts. In everyday English, 'log in' is the safer choice.

Can I say 'I am logging in to the website right now'?

Yes, the present continuous is perfectly natural here. It describes an action happening at this moment, for example while you are waiting for a page to load. This form is common in everyday speech.

What kinds of things can you 'log in to'?

You log in to anything that requires a username or password — for example, your email account, a social media platform, an online banking site, a school portal, or a work system. The phrase is used for websites, apps, and computer networks.

Do I always need to say what I am logging in to?

No. When the context is clear, you can simply say 'log in' without mentioning the system. For example, 'Just log in and you'll see it' is completely natural. You only need to add 'to your account' or similar if it helps make your meaning clear.
