I mean, realistically, you should be using group checks instead of individual checks for stealth like this IMO
password managers in the browser still store them encrypted. They usually authenticate via a passkey, in-built security in the OS like windows hello, or through other services such as SSO through google; That said, if you have them on auto-pilot with this authentication, anyone with access to the device can theoretically access them, though to actually view them in the password manager they usually require you to authenticate.
Browser password managers are sorta less secure than a third party one, assuming you turn on all the convenience features to make your life easier, but a lot of third-party password managers have the same convenience features a lot of the time anyways.
Saving the password in your browser is using a password manager; you're just using the one built into your browser. The safety and security of using any individual password manager is pretty much up to how secure that particular password manager is, but generally speaking they all store passwords encrypted.
Ones built into a browser have the added attack vector of being potentially vulnerable from the browser itself vs a stand alone manager, but if you use a plugin for your favorite password manager they likely share a pretty similar attack vector possibility.
Either way, using a password manager is infinitely better than reusing passwords, so this is really just a long winded way of saying "no, not really".
Dedicated password managers usually come with more security, control, and features, but you're generally going to be fine using the one built into your browser.
Brandon's bard in a box from 2e.

off the top of my head, gamma world, mutant crawl classics, Mutant (and its more modern version mutant year zero).
Mutants and masterminds depending on your definition of mutation, since its more like "superhero marvel mutants" than like "radioactive mutants"
Monte cooke games also has a 5e supplement called "arcana of the ancients" that includes mutation rules that are pretty good IMO.
I dont know if it will include it, but i am like 90% sure the upcoming mystic punks from exalted funeral is going to have something to do with mutants.
Me as a DM critting a player:

I mean, I liberally plumb other systems for content in general, so relatively all the time. Mechanics, setting, anything I can pull that sounds good to me.
The gold market cap has always been the approximate amount of gold that has been extracted. While I don't think anyone can give you an actual precise number, the approximate number is pretty widely known and tracked as we extract more.
"His majesty the worm" uses a deck of tarot cards, minor arcana for players and major arcana for the GM. Combat plays as a sort of "poker game"
I really like the sentinels comics rpg - https://www.greaterthangames.com/pages/sentinel-comics
It's based on the sentinels of the multiverse card game, and has a really unique system. Basic low down - every roll you have die based on a "stat", a power, and your (or the scene's) status (green, yellow, red).
On a basic roll, you always take the middle die as your results. Powers might alter this or do something extra.
So for example, let's say you have super strength as a stat for a d8, a power die of a d6 for the power you're using, and a d6 for your current status (green). You'd roll all three of these and take whatever value is the "middle" result (so like d8 - 2, d6 - 4, d6- 5, you'd get a 4).
Powers might do something like "deal damage equal to the lowest die, but heal an ally for the middle die" or "deal damage with the highest die, but take a penalty equal to the lowest die"
im pretty sure its the other way around; If they hold out for 1 more month, they have to have a special election. If they don't hold out for a month, the governor (who is a democrat) gets to appoint someone.
