Six locks and keys
The emoji list files six emoji under lock: Locked, Unlocked, Locked with pen, Locked with key, Key and Old key, all from Emoji 0.6 or 0.7. CLDR, Unicode's list of search words, gives private to 🔒 alone, secure to 🔐 alone and password to 🔑 alone.
A lock where emoji are dropped
Some name fields lose emoji. ⚿, Squared key, is plain text, and Unicode's notes call it parental lock. [⊙] draws a lock in three characters. The ASCII padlocks line up only in a monospaced font.
- 🔒 and 🔓 have text forms, so the Text style switch turns them black and white. 🔐 has none.
- For a locked in post, the combo 🔒🧠 is ready: locked, then brain.
- No emoji name or search word holds padlock or vault. Unicode's notes do call 🔒 padlock in locked position.
Questions and answers
What is the lock symbol in text?
⚿, Squared key, U+26BF, is a character, not an emoji, so it keeps the colour of your words. 🔒 with the text-style selector, 🔒︎, asks for a plain lock too, though a device may still colour it.
What is the difference between 🔒 and 🔐?
The key. 🔒 is Locked, the padlock alone, which CLDR files under private. 🔐 is Locked with key, the only emoji filed under secure, and it has no text form.
Is there a keyhole symbol?
Yes, , Keyhole, U+1CEB1, but it arrived in Unicode 16.0, so many devices still show an empty box. ⊙, a dot in a ring, works as a keyhole in the meantime.
