A digital letter with a password, meant for one person
Written by hand · Sealed with wax · Sent as one link
An email or a chat message sits in a thread that can be forwarded, scrolled past or glanced at over a shoulder. A letter with a password works differently: the reader needs the key you gave them. Write it the way you would write to someone you trust completely, and choose a password that only the two of you would connect to each other.

Ways to begin
“I put a password on this letter because it's meant for you and nobody else.”
“If you're reading this, you remembered the password, and that's exactly how I knew it would reach the right person.”
“There are things I've never said out loud, so I wrote them down somewhere only you can open.”
What to write
1. Choose a password with a private meaning, like a nickname, a street or a joke only you share. Avoid birthdays and first names, which are easy to guess.
2. Send the password a different way than the link. Tell them in person or on a call, not in the same message as the link.
3. Make the letter itself personal: use real names, a specific date, a detail only this person would recognise. A private letter should read like it could not have been sent to anyone else.
Frequently asked questions
Q. How do I pick a password for a private letter?
Pick a word or short phrase the recipient will remember easily but a stranger would not guess, such as the name of a place you both know. Give it to them separately from the link, ideally by voice or in person.
Q. Can anyone who gets the link open the letter?
If you set a password, only the people you tell it to can open the letter. The password is optional, so without one anyone holding the link can open it. The recipient opens the link in a browser with no app and no sign-up, and writing, sealing and sending are free.
