(CNN) -- Your husband, an avid gamer and techie, dies of a heart attack, leaving his vast online life ­-- one you don't know much about ­-- in limbo.



Eternal Space lets loved ones create customized online gravesites and memorial pages.



His accounts, to which you don't know the passwords, go idle. His e-mails go unanswered, his online multiplayer games go on without him and bidders on his eBay items don't know why they can't get an answer from the seller.



Web site domains that he has purchased, some of which are now worth hundreds of thousands of dollars,­ will expire, and you may never know.



It's a scenario that's becoming more likely as we spend more of our lives online. And it's raising more questions about what happens to our online lives after we log off for the final time.



The answer, until recently, was nothing.



But now, as online usage increases and social-media sites soar in popularity, more companies are popping up to try and fill that void created in your digital life after death.



Jeremy Toeman, founder of the site Legacy Locker, recognized that when he was on a plane and wondered what would happen to his online life if it crashed. While his will leaves everything to his wife, including all of his digital assets, Toeman realized how difficult it would be for her to access his accounts.



"My GoDaddy account would belong to her, but it doesn't solve the practical reality of how she would get access to it," he said. He experienced a similar scenario after his grandmother died, and he tried to get the password for her e-mail account -- only to give up because of the hassle.



So Toeman built his company to change all that. Legacy Locker allows users to set up a kind of online will, with beneficiaries that would receive the customer's account information and passwords after they die.



"We know it's a hard thing to think about -- to get people to face mortality. We know it's kind of morbid, but for those who live their entire lives online, it's also very real."



A Legacy Locker account costs $29.99 a year. Users can set up their accounts at www.legacylocker.com to specify who gets access to their posthumous online information, along with "legacy letters," or messages, that can be sent to loved ones.



If someone contacts Legacy Locker to report a client's death, the service will send the customer four e-mails in 48 hours. If there's no response, Legacy Locker will then contact the people the client listed as verifiers in the event of his or her death. Even then, the service would not release digital assets without examining a copy of the customer's death certificate, Toeman said.



Eddie Lopez is the kind of tech-savvy guy for which a service such as Legacy Locker was made. The St. Paul, Minnesota, man has three online banking accounts, a PayPal account, domain names, Web-hosting accounts, multiple e-mail addresses and many social-networking accounts.



"I do think this is something people should be really considering these days," Lopez told CNN when asked about services such as Legacy Locker. He wants to hire a service to handle his digital assets but is concerned about privacy.



"Although I'm glad there's people breaking ground in this area, I don't think I would jump at the first opportunity to sign up," Lopez said. "My concerns are turning over such an exhaustive list of user names and passwords to a single business. That's one-stop shopping for any hacker to get access to just about every detail of my life."



Lopez would prefer to entrust half of his digital-security information to a service such as Legacy Locker and the other half to family members, so that each side's information would be useless without the other's.



"I hope Legacy Locker and similar services can address these privacy-security concerns with some real-world solutions,
