I don't like saving my password on PM because it can be compromised not to talk more of saving your seed phrase on a PM. It's good that you engrave your seed phrase on a stainless steel and keep them in different locations. However, one needs to be very careful with whatever method he chooses to use to keep his seed phrase save so that he does not make it vulnerable to a third-party.
Or alternatively you can probably change some of the words in your phrase that only you can know so even if it's stolen you're the only one who can access it.
It's not advisable to change any word of your seed phrases or abbreviate it because if there's any accident in future that make you lose your memory, you funds is gone. Better to add a passphrase to your seed phrase.
For another layer of security, you can put your seed phrase in a password-protected PDF file
(Microsoft Word gives you this option). Then upload it to your PM.
My caveat would be all this stuff is for more advanced users. You don't have to be super tech savvy
to use them but should be at least moderately computer savvy and feel very comfortable doing this kind of stuff.
Those who don't feel comfortable dealing with too much complexity, it's best to keep it simple and stay with offline-only storage.
