Generate a random alphanumeric string when a row is created. Use for invitation codes, single-use tokens, unique slugs, or anything else where you need a non-guessable identifier.
Conditional options
- Length of String (Required) — how many characters long. 12 is a sensible default for invitation codes; 32 or longer for opaque tokens.
How it's generated
At row creation, the platform generates a random string from the alphanumeric character set [a-zA-Z0-9]. The field is read-only on the form — users can't enter their own value (which would defeat the purpose).
Common uses
- One-time invitation codes for new users.
- Magic-link tokens for passwordless login.
- Short unique IDs for sharing URLs ("/share/AB12CDEF").
