In a thread on Reddit's Life Pro Tips, several users contributed their experiences to come up with a list of public password suggestions. Usually, restaurants and stores make their wireless password something related to the venue.
Here's a list of things several users have found to work. If you're stuck without access to the network's password, go down the list and try one or more of these suggestions:
• [the venue's] phone number (with area code, but without hyphens)
• street address
• restaurant/store name
• something popular in the restaurant/store
• location backwards
• default passwords (e.g. "admin," "password," "asdf1234," etc.)
Of course, there's no guarantee that any of these will work, but it's a good place to start if you need after-hours access to public Wi-Fi. If you have any other suggestions, add them to the comments!
