Birdsuite Seal
Hand over credentials securely: encrypted in your browser, readable exactly once – then gone for good.
Passwords do not belong in emails or chats – they stay readable there forever. With Birdsuite Seal you create a sealed link instead: the recipient opens it exactly once, then the secret is irrevocably deleted.
Seal works on a zero-knowledge basis: encryption happens in your browser, the key is part of the link itself and never reaches our servers. We store nothing but the encrypted content – until it is revealed or its expiry passes.
Seal is free and works without an account. Seal Pro notifies you by email the moment a secret is revealed and lists your open seals in one overview – for €3 per month or €30 per year.
What Birdsuite Seal can do
- Read once, then gone
- Each seal can be revealed exactly once – afterwards the content is irrevocably deleted. Unopened seals expire on schedule.
- Zero-knowledge encryption
- Encryption and decryption happen in the browser. The key stays in the link – we could not read your content even if we wanted to.
- Expiry windows
- You decide how long an unopened seal stays valid – after that, Seal cleans up automatically.
- Reveal notifications (Pro)
- Know immediately when your secret has been opened – and keep track of open seals in one place.
Who is it for?
For IT teams, agencies and everyone who needs to hand over credentials, API keys or confidential notes – without leaving them sitting in inboxes and chat histories forever.
Frequently asked questions
