Public Wi-Fi · Email guide
The portal needs an address that can receive email, but it doesn’t have to be your primary one. Check what it’s for before deciding which key to hand over.
Temporary email is receive-only. It can’t replace identity, room-number or payment verification, and not every portal accepts it.
A confirmation email will be sent to the address below.
Email addressHotels / airports / cafés
Before entering an email for public Wi-Fi, check whether it’s only to confirm this connection. These are common scenarios, not rules for any specific provider; follow the portal’s guidance on wait times.
Hotel stay
Hotel Wi-Fi may only verify your email, or it may also ask for your room number and name. Don’t use an address that expires for reception records, bills or checkout notices.
At the airport
Airport Wi-Fi may require an email, text message or another type of verification. If you only need one confirmation email, a temporary address may work; keep flight and baggage updates in your primary inbox.
Quick stop at a café
Some portals also offer marketing emails. Read the consent text and distinguish Wi-Fi terms from optional promotions. Using a temporary address doesn’t mean you should ignore what you’re agreeing to.
If the email hasn’t arrived, the address may still be correct. A device that isn’t online may not be able to open its inbox yet. Try accessing the Tmpkey inbox using mobile data, or ask staff how to connect.
Check first, then share your address
Whether it’s safe to enter an email for hotel Wi-Fi depends on more than the email field. First check that the network name and portal are official, then consider these three questions.
If the page asks for an ID, phone number, room number or guest name, email confirmation is just one step. Follow the provider’s verification process; a temporary email can’t replace those details.
Not sure the portal is legitimate? Check with the front desk or staff first.
If the address will also be used for bills, a membership account, complaints or password recovery, you’ll need continued access to it. Temporary addresses expire and can’t be recovered, so they’re not suitable for these purposes.
Need to stay reachable? Use your permanent email or a forwarding alias.
Read the notes near the email field and the terms of use. Some networks block disposable email addresses; being able to enter one doesn’t guarantee verification will succeed.
If temporary addresses aren’t allowed, follow the rules—don’t keep trying new ones.
Use a temporary address only if you need to confirm this connection, don’t need follow-up contact and the provider allows it.
See the stepsHow to use the portal
Keep the portal and Tmpkey open in separate pages, then follow the steps below. All addresses, codes and screens shown are examples; nothing will be submitted.
Tmpkey
Open the home page and copy your address once it’s generated. Don’t copy the example address shown here or mistake the demo email for a real message.
Open anonymous inboxReturn to the provider’s official portal and paste the full address. Check for missing characters or spaces. Read the terms, then submit the email confirmation request.
Keep using the same address and wait for the email to arrive. You can also refresh the home page. If it doesn’t arrive, check the portal submission and address before requesting another email.
Check that the sender and link destination belong to the provider. Enter the actual code in the portal or use a trusted confirmation link, then return to the portal to confirm you’re connected.
Waiting and expiration
After submitting the portal form, keep using the same address. Changing or deleting it before confirmation could leave you unable to read a code or link sent to the old address.
Check time remaining on the home pageEmail lifetime and Wi-Fi access time are separate. The provider decides when access ends and whether you need to verify again.
If it’s not accepted
A portal may block disposable email or delay sending a message. If submission fails, you don’t need to keep generating new addresses—and you must not use them to bypass network requirements.
If the page requires a particular type of email, payment credentials or identity details, follow its instructions. Passing an email check doesn’t let you skip those steps.
Show the error message to the front desk or staff and ask whether temporary email is supported or another official verification method is available. Never share a code from an email with a stranger.
If you need follow-up contact, use your permanent email. If the portal allows it, you can also use a forwarding alias to receive messages in your regular inbox; aliases aren’t guaranteed to be accepted either.
Manage email aliasesIf you’re not comfortable with the information or terms the portal requires, use mobile data or another trusted network. Don’t use a temporary email to bypass payment, identity or access requirements.
Privacy limits
A temporary email reduces direct exposure of your primary address. It isn’t a VPN, doesn’t change how you connect to the network and can’t erase identity details already recorded by the hotel.
Your IP address, connection time, device or browser details, and information such as your room number or phone number that the provider collects under its policies or applicable law. What’s visible depends on the network setup and provider policy—not Tmpkey.
Never enter your primary email password, payment password or other unrelated credentials in an unfamiliar portal. A temporary email only receives messages; it can’t prove that a hotspot, sender or link is safe.

Make sure the portal allows it before copying an address. Keep the inbox open until verification is complete.
