Also, I thought it would not matter much what service of password managing one chose?
Because as far as I understood during my brief investigation, the data is encrypted and decrypted using the trezor itself?
Data with login details and passwords on Trezor was encrypted, but I don't know how exactly and it's possible they identified some weakness because web browser must be used for this to work.
It sure matters what password manager someone is going to use after Trezor Password Manager, and I wouldn't recommend using LastPass or anything like this.
I don't expect someone decide to continue maintain it when more established alternative exist and currently there are almost no contributor.
It's not impossible to happen.
There are several hardware wallets that exist today and they are Trezor forks, like KeepKey, OneKey, Prokey, etc.
OneKey is biggest Hardware Wallet company based in China, and they could easily continue with OneKey forked Password Manager.
1Password (which mentioned on Trezor website as alternative) also had few security incident and IMO should be avoided.
Yeah, I think Trezor needs to update that page asap.
