Is secret always 51 chars?

Help
1

Just a quick question.
Secret after login seems to be 51 chars, is that always 51 or can it change its length?
(I’ve searched on forum and docs but it seems to not be mentioned anywhere)

There is a time-based component used during secret generation. While you might commonly find secrets to be 51 characters in length, it is not guaranteed that a secret would always be that length.

I’m curious: how does the length of a secret matter for your use case?

It was for unit testing purposes, so no use case as such.
Thanks for answer.
