Is it possible for a hacker to get my Hotmail password without access to my computer?

The hacker could guess it.

I'd venture a guess that the most common form of account theft and password hacking is simply being able to guess your password. I'd go even further to say that this is perhaps the most common among children.

Yes, having a password that's easy to guess is at odds with being able to remember it yourself. To put it bluntly: too bad. You need to come up with an approach that you can remember and that no one would ever be able to guess.

What's a good password? discusses this in some more detail.

The hacker could have found your notepad.

Do you write your password down on paper somewhere?

Don't.

It's just another way that someone could stumble upon it and then use it to access your account.

In particular, keeping it written down anywhere in, on or around your desk, workstation or computer is just asking for trouble. Use a password method that you can remember, something that you don't have to write down.

You could have told the hacker.

You may think I'm joking, but I'm not.

Have you ever shared your password with anyone?

ANYONE?

I honestly don't care if that other person is someone you really, really trust. Boyfriend, girlfriend, trusted colleague, "BFF" ... it doesn't matter. You've just given your password to someone else.

Yes, they could be the hacker, I suppose, and that does happen - often. But even more frequent is that they inadvertently share your password with someone else. Someone else that you don't trust, and that someone else becomes your hacker.

I'd also guess that this is also one of the more common reasons for account theft and hacking among children.

You could have told the hacker, again.

There are many ways that hackers try to get your password. The one we're most familiar with is the phishing scam. Email that looks like it's real, email that asks you to go somewhere that also looks like it's real, where you're instructed to enter your account ID and password.

The only problem is that it wasn't real. It was a hacker attempting to collect your account information.

Similarly, there are services out there that add functionality to Hotmail - perhaps a POP3 connector, or a social media site wanting to import your contacts. But to do so they need your account ID and password. By giving them that information you're assuming that they are trustworthy. Many are. Many are not.

You could have told the world!

Ever use an open WiFi hotspot?

This is less likely, since Hotmail's default login is, in fact, secure, and your password should not be visible to WiFi sniffers nearby.

On the other hand, if you use one of the POP3/SMTP connectors for Hotmail, it's unclear whether your password is transmitted in the clear. If it is, it's there for anyone nearby to see.

It might not have been Hotmail

Recall that most people use their Hotmail ID for Windows Live Messenger, and a number of Windows Live and MSN services. For example you might have given someone your MSN Messenger password, not realizing that's exactly the same as giving them your Hotmail password, because it's the same account.

The hacker might have access to your computer.

I know you excluded this in your question, but I have to include it. The hack could get your password via spyware installed on your machine. That spyware could be recording everything you do, just account ID's and passwords, or anything in between. That collected data is then sent off to the hacker.

It's one of the biggest reasons I so strongly recommend taking all the steps necessary to keep your computer safe.

The bottom line is that it is all in your control.
