Public networks · Email guide

What email should you use to connect to public Wi-Fi?

Connected to a hotspot but stuck on an email form? First check whether it needs a one-time confirmation or an account you’ll need to access again later.

If you only need one confirmation email to get online and the venue allows temporary email, use an address that expires after a set time. For bills, refunds, or account recovery, don’t rely on an address with a countdown.

Form field example

Enter an email address

Read the network terms first and check how your email will be used.

Email address lindazhou@tmpsky.com
Some portals only record your address; others send a confirmation email.

Marketing emails aren’t needed to connect. If the option is optional and you don’t want them, leave it unchecked.

This illustrates a form field; it isn’t a real Wi-Fi login form. The example address can’t receive email. Go to the home page to copy an address that’s actually been generated.

What email should you use for public Wi-Fi? Check these three requirements

Check the instructions near the submit button, and whether you’ll need the account again after connecting.

01 · Email address only

Connect after submitting

The page asks for a contact address, then connects you without asking you to open your inbox or click a link.

Could work
If the rules allow it, use a temporary email address for this sign-up.
Not a good fit
The page says bills, deposit refunds, or service notices will be sent to this address.

02 · Email verification

Verify your email to connect

The page asks you to check for a verification code or click a confirmation link. You need an address that can receive email; entering a made-up address won’t work.

Could work
A temporary email address that stays active long enough to complete verification.
Not a good fit
You can’t access your inbox until you verify the network, and you have no other connection, such as mobile data.

03 · Ongoing account

You’ll need to log in again later

Airport memberships, hotel loyalty programs, and multi-day Wi-Fi plans may require you to log in again, renew, or recover your account by email.

Use instead
An email address you can access long-term, or a forwarding alias accepted by the venue.
Not a good fit
A temporary address that will expire as your only account recovery option.
Compare the three types of email address

A correctly formatted address doesn’t guarantee the venue will accept it. Tmpsky can’t guarantee portal approval or bypass identity checks or payment requirements.

Keep your inbox within reach

From the portal to your inbox: four steps

A Wi-Fi login window opened by your phone may not let you keep multiple tabs open. Plan how you’ll get back to your inbox first.

  1. 1

    Open Tmpsky

    In a regular browser, open the home page, then wait for an address to be generated. Don’t use the example address on this page as your own.

  2. 2

    Copy the full address

    Use the copy button next to the address and make sure it includes the full @tmpsky.com. Check how much time is left. Extend the address if you need more time to verify.

  3. 3

    Return to the portal

    Paste it into the email field, read the network terms, then submit. Don’t enter an email verification code in the room number, phone number, or password field.

  4. 4

    Go back to your inbox

    Return to the inbox you already opened and wait for it to refresh. When the email arrives, enter the code or open the confirmation link as directed by the portal.

You’re verifying the network, not your email password

Open the confirmation email and check its details

A familiar subject line doesn’t prove an email is genuine. Check the sender address, verification code, and link destination separately.

  1. Check the sender. Display names can be faked. Expand the full sender address and compare it with the provider details posted by the venue. If you’re unsure, ask the front desk.
  2. Use only the code you need. Enter the verification code only on the authentication page you opened yourself. If it expires, request a new one instead of repeatedly submitting the old code.
  3. Check where the link leads. On supported devices, hover over or long-press the link to see its URL. Check the full domain and HTTPS, and watch out for lookalike domains.

A routine Wi-Fi email confirmation won’t ask for your email password. Stop if a page asks for your email password or payment details, or asks you to install an unknown certificate.

Example

Confirm your network connection

You just submitted a guest network request. If you did this, enter the verification code on the authentication page.

Example code · Not valid 583 104

Some portals send a confirmation link instead of a code. Check where it leads before opening it.

This is an example for reference, not a real email or working link;.example is a reserved example domain. Check your actual messages in the inbox on the home page.
If verification fails, find out why

Three common roadblocks and what to do instead

Don’t keep trying different addresses at random. The error message often tells you what to do next.

Domain blocked

Temporary email not accepted

This is the venue’s or network provider’s email policy, not a formatting issue. Trying another address on the same domain usually won’t help.

Use an address you can access long-term that the venue accepts, or contact staff. A forwarding alias may also be blocked; don’t use one to get around an explicit restriction.

Email hasn’t arrived

Submitted, but no email yet

First, check that the full address in the portal matches and check the inbox countdown. Then make sure you can access Tmpsky on your current connection. Try refreshing once; repeatedly requesting another email may trigger the portal’s rate limit.

Wait as long as the portal advises before requesting another email. After resubmitting, use the latest verification code. If the email still doesn’t arrive, ask staff to check delivery or use an email address you can access long-term.

Identity requirements

Room number or identity details also required

Email is just one of the fields. A temporary address can’t replace proof of guest status, SMS verification, identity checks, or eligibility for a Wi-Fi plan.

Provide your own information as required by the venue. If you’re unsure why something is needed, ask first. Don’t enter someone else’s room number or ID details, or try to bypass verification.

After you leave the hotspot

Your connection may end; follow-up messages may not

A one-time confirmation is easy to leave behind. Money, bookings, and accounts need a different plan.

Don’t let the email you use for public Wi-Fi become your only way to be contacted during a trip. Check where hotel bills, deposit refunds, booking changes, and membership recovery messages will go before using a temporary address.

When to use a temporary address

  • You only need it to connect this time, and the venue allows it.
  • You can finish verification before it expires, with no need to recover the account later.
  • You won’t use it as the only way to receive payment, billing, or important booking notifications.

Addresses generated on the home page are currently valid for 3 hours. Each extension adds 3 hours; check the live countdown and the result of each extension. Once an address expires, is replaced, or is deleted, don’t expect to retrieve messages sent to it.

Choose what you need before copying

Need an address just to connect, or one you can keep using?

For one-time verification, get an address on the home page. For ongoing email, go to the separate sign-in page to set up forwarding.

Follow the venue’s network rules. The portal provider decides whether to accept an address.
