In plain English
Capital and small letters count as distinct characters. Because of that, text with the same letters does not match if the letter case is different.
In context
Here, it warns that the password rules compare uppercase and lowercase letters separately, so a different letter case means the text is treated as different.
- Situation
- Setting passwords, multifactor authentication, recovery codes, and trusted devices
- What it communicates
- warns about letter-case matching in the password rules
Meaning limits
By itself, the term says only how letter case is compared, not any other rule about what text is allowed or accepted.
Examples
“The filter is case-sensitive, so it treats "Map" and "map" as different entries.”
“Since the password is case-sensitive, he checked whether the first letter was capitalized.”
