Situation:
Five or more PIN code patterns, each pattern goes from four to eight or more digits, depending on the platforms' or services' PIN code options, which are repeatedly set on multiple platforms in various lengths, non-unique PINs.

Details:
Pattern for non-sensitive things like opening car-sharing cars, profile access on any streaming service shared with others, pattern for identifying in front of service employees for support requests.

Current setup:
Like crypto asset details, PIN codes are saved in text notes and there is no effective and intuitive management.
One note for each pattern, splitting pattern into length variation categories, into which said use-case is added.

Example:
Note name: "PIN Codes [Public]"
Note content:
"Four-digit:
- Amazon
- Google

Six-digit:
- Protonmail
- Youtube

Eight-digit: ..."

Have a great day, Proton team!
