Summary15026: Omit ambiguous characters from token
DescriptionIn tokens you can specify the length, but not the characters that are used.

In our use case we have difficulties using the characters: O (cipital o), 0 (zero), l (lower case L), I (capital i) and 1 (one) that are ambiguous (depending a bit on the font that is used to show them).

In our use case these tokens are sent by mail (on paper) and users have to type them in like a password. Ambiguous characters then influence the response rate in a negative way: once entered a wrong code, people tend to turn away.

We propose to change the tokens in such a way that ambiguous characters are replaced.

We will make a pull request as soon as this is discussed enough here.
TagsNo tags attached.

This is really a **needed** option, most of

Seems i'm the only one

If we accept only numeric, why not all the other :

Since no new feature in 3.X : for 4.X.

@JanE : your pull request seems great. Just let me test before merging (and quick discuss at today dev meeting)

@c_schmitz : see discussion about have this feature in 3.19

PS : my opinion, why not BUT : why not other minor feature (like adding a function in twig …)

Hello there,
sorry for revamping an old ticket. It was quoted on my forum's topic: Token creation algorithm by @DenisChenu

I'm asking the feature for having human readable tokens because people get scared reading a complex nonsense string.
So I would like to thanks the team for the effort, I'm trying to backport it shortly inside my 3.x installation before having a full 4.x LS adoption.
