Different Length OTP Variants Input OTP for Solid

Three code fields on one page: four digits in a row, six digits in two groups, and eight digits in two groups.

UI library: Ark UI

Three labeled fields stack on the page. 4-Digit OTP is four boxes. 6-Digit OTP is two groups of three. 8-Digit OTP is two groups of four.

Match the length to the code you send. A single Input is easier when the length is not fixed. In Solid, Ark UI moves to the next box as you type.

FAQ

How is each length set?

The number of InputOTPSlot parts sets the length.

How should I group each length?

Short codes read best in one block. Split longer ones in the middle, as here: three and three for six digits, four and four for eight, with an InputOTPSeparator between the groups.

How do the indexes work in the eight-digit field?

They count through the whole code, 0 to 7: 0 to 3 in the first group and 4 to 7 in the second.

How is each field labeled?

Each sits in its own Field with a FieldLabel: 4-Digit OTP, 6-Digit OTP and 8-Digit OTP. Field links each label to its code field.

Which length should I use?

Four digits for short-lived PINs, six for SMS and email codes, and longer ones for backup or recovery codes that are typed rarely and need more strength.

Do the fields stretch?

No. Each is as wide as its slots, so the eight-digit field is the widest. The fields are stacked with gap-6.
