I have all my passwords and stuff in an Open Office Write document (.odt file) in Dropbox. That file is itself password-protected (which effectively means it is encrypted with the password being the key).

I'm happy with this approach generally (I'm not looking for advice on whether it's secure enough, thanks), but the one problem is that the Dropbox app on my iPhone can't handle the password-protected aspect - it just says "Unable to open file". It'd be very handy to be able to access this info on my phone while i'm out and about, but I don't want to put it in Dropbox in an unencrypted format.

Does anyone know of a different password-protected text file format which will work in the Dropbox app? Ie will ask me for the password then open the file?

Alternatively, can anyone recommend a different app which syncs between devices and does password protection, and works on iphone? I don't mind a one-off payment but i'd prefer not to have to do a monthly subscription. Also i'd prefer something that has freeform text entry rather than something that just stores usernames and passwords because sometimes I have to write notes about things.

EDIT: It was suggested in the comments to use the Notes app, and i've just tried that. Unfortunately, because i'm using a different icloud account on my work computer as on my phone, I need to do it as a "Shared Note", and shared Notes can not be locked (ie password protected). So I think Notes is not going to work unfortunately.

EDIT2: The Notes app on iphone, combined with being logged into icloud.com in the web browser on my work mac (rather than using the native Notes app on the mac) seems to be working - both the iphone Notes app and the website require the password (which is different to the password to log into the icloud.com website) to view the contents of the file, which is what I needed.
