Hi cyrillschreiber,
Good news, we've built this capability and it's planned for our next major version, coming in September . It does exactly what you described — the date lives inside your fixed pattern (not just appended at the end), the static part stays exactly as you type it, and only the month/year updates automatically.
You'll create a password template in Pattern mode, for example:
'FinanceApp!'{date:MMyy}
That produces FinanceApp!0626 this month and FinanceApp!0726 next month. The text in single quotes is kept verbatim, and {date:MMyy} inserts the current month and year — you can use any date format you like ({date:yyyy-MM}, {date:MMyyyy}, etc.).
Because password rotation generates the new password from the selected template, you can assign this template to your managed accounts and have the date advance on its own with each scheduled rotation (monthly or yearly), while the rest of the password never changes.
A couple of notes:
If you ever want a bit of entropy alongside the fixed convention, you can add a random segment, e.g. {random:6}.
As with any fixed/predictable format, we'd recommend using it only for the specific cases where your environment requires it.
Thanks again for the detailed use case.
Best regards,
