¯×5fl\©^ò'H:´¨!éuÕäàóÐiC4¼_-µ=Þª¶±Àj is a pretty strong password, one that's practically impossible to type using your phone's touch keyboard, and a real PITA to try and type with a PC. With a password mgr. it's a cinch however, to both generate & later copy/paste such a beast. And That's the strongest argument in favor of password managers.
The rule of thumb with password storage, or most anything related to security, is that easiest is weakest -- IOW security costs in time, lack of convenience, & sometimes money. Lots of people and companies take the approach that once someone has access to your device, it's game over -- if nothing else malware can just wait until a password is copied into memory and grab it. From that perspective, storing your passwords in whatever browser is fine -- it may be relatively easy to get all the stored passwords out of the browser, but if they have that kind of access they could get them anyway. And that's why there's two factor authentication, which requires two forms of ID, e.g. both a password and something physical, whether that's a finger print or a cell phone. It's not impossible to beat, but it's a step in the right direction.
Companies like Microsoft use something they call Zero Trust on their own networks & systems -- basically it means assume you've been breached, trusting no device or person, requiring layers of authentication supplemented by AI monitoring of all activity.
What you use is up to you, and how you use your passwords, i.e. what you use them for, has a lot to do with it. It might be a pain, but also financially irrelevant if someone(s) nabbed your password to whatever forum, so you don't have to store that password in the most secure manner -- passwords for PayPal, Amazon, your bank(s) etc. are an entirely different category. If you always have a cell phone handy, Microsoft's Authenticator might be a good fit, since it can be used for both 2 factor authentication and manage/store your passwords across multiple devices. If you're more security prone or paranoid [take your pick], a completely offline password manager using a key, plus optionally a password might be a better fit. KeePass for example lets you use a special text file it creates as a key, which can be stored securely on removable storage, like a USB stick or micro SD card. Or you can opt for something like a FIDO key.

Regardless what you use, bear in mind that [almost] nothing is forever, so you need to be able to get your passwords back out of whatever manager and into a new one. And bear in mind that you are not the only variable -- you can have the strongest password and use two factor authentication, but if the site where you use it has poor security, anything you enter, say a credit card number, could be up for grabs.
