Share username and password combinations securely. Perfect for shared accounts.
A login credential is a pair, not a single string: a username (often a recognizable email address) plus the password. The combo is what credential-stuffing attackers trade — Have I Been Pwned and SpyCloud index the pair, because every dump is keyed by email. Streaming services, utility portals, and retail loyalty programs live in pair-shaped territory.
Households reach for iMessage, fridge sticky notes, or the Notes app synced across the family Apple ID. Netflix, Disney+, Hulu, and Spotify Family rolled out household-verification through 2023 and 2024 that fingerprints device clusters; once your combo escapes, an unfamiliar IP triggers a reset prompt to the account-owner's email. Comcast and most regional electric providers retain billing-portal message threads for years.
PasteOnce sits between the moment you type the pair and the moment the recipient reads it. Paste the website plus username on the first line and the password on the second, generate the link, and send it through whichever family chat thread you usually use — the link is opaque without the URL hash. Pair the handoff with a force-reset on services that allow it, or a logout-of-all-devices toggle on services that do not.
Client-side encrypted. We can't see your data.
Your data is encrypted in your browser before it leaves your device.
Messages are automatically deleted after being read once.
We never see your data. Only encrypted blobs pass through our servers.
Links work exactly once. Refresh the page and it's gone forever.
Your sensitive data is encrypted in your browser using AES-256-GCM. The encryption key is generated randomly and never sent to our servers.
Only the encrypted blob is stored in our database, with an automatic expiration time. We literally cannot read your data.
When your recipient opens the link, the encrypted data is fetched and immediately deleted from our servers using an atomic Redis GETDEL. The key in the URL hash decrypts the message in their browser.
Send the website plus username through one app — say, an iMessage thread — and the password as a PasteOnce link through a different one such as Signal or WhatsApp. Single-channel interception now yields half a credential, which is useless.
1Password Families, Bitwarden Families, Dashlane Friends & Family, and the iCloud Keychain shared-group feature all expose a per-account vault to a defined household. Use PasteOnce to bootstrap the first device; thereafter the vault is canonical.
On Netflix, click Sign Out of All Devices in account settings; on Spotify, hit Sign Out Everywhere; on Disney+, use Log out of all devices. The recipient logs back in and any prior session ghosting on a forgotten device evaporates.
Have the recipient set a new password the moment they log in, generated by their own password manager. The combo you typed becomes a stale string in your clipboard rather than a live key sitting on someone else's screen.
Your daughter moves into a dorm and needs the Hulu login from the home TV. Email goes to her old high-school address; iMessage syncs through her brother's iPad. PasteOnce instead, she logs in once, link evaporates.
You fly out for a week and your partner needs the Comcast or AT&T login to chase a billing dispute. The portal locks new-device sessions behind email-OTP. PasteOnce the pair, they log in, and the session persists for the trip.
A neighbor watches the dog for a long weekend and needs the Ring camera feed. PasteOnce the Ring login, they sign in, watch the dog, and Sunday night you hit Sign Out All Sessions and rotate before they close the tab.
Depends on each service's household definition. Netflix's terms restrict sharing to a single household and offer a paid Extra Member slot; Disney+ has parallel paid-sharing pricing in the US since 2024. Spotify Family checks the address. PasteOnce makes the transfer safer, but does not change what each service permits.
Paste both lines into a single PasteOnce note — website, username on one line, password on the next. The link is safe to send through any chat tool because the encryption key sits in the URL hash, which never leaves the browser address bar.
PasteOnce has no recall button, but you do not need one — the link self-destructs on first read. To revoke account access, go to the service's security page, change the password, and use the Sign Out All Devices control most major providers expose.
Those are excellent for ongoing access inside one ecosystem, but they assume the recipient is on iOS or Chrome with the matching account configured. PasteOnce works across ecosystems — iPhone-to-Android, parent-to-grandparent — and requires no install or signup.
