Personally i use keepass on pc and smartphone. (Has an android app) . Database and key file are stored in the cloud (Dropbox) and i have one master password. It has a pw generator if you want to generate long ass random passwords for exchanges or wallets. There are some the threads in ot with other suggestions. 1pass and lastpass are mostly mentioned.
Ok thanks. A smartphone app does sound handy but storing the database and key file in dropbox? Google Drive would be fine aswell then? Can have as many backups as you want right?
Edit: and the master password is written down??
