I’ve been using CodeBook for several years and have been pretty happy with it. One time cost (per OS) and can sync over WiFi or to Dropbox/google drive. No browser plugins, instead it provides a global hot key activation which authenticates you (Touch ID or password), lets you search for the account then auto-types the password. On iPhone it integrates well for providing passwords to sites and they just recently added a feature which will also auto-copy 2FA TOTP into clipboard if one exists.
