Buenas !!!
Una utilidad que parece muy interesante https://cyapass.com/.
Using CYaPass
All you have to do is:
Add / Select a SiteKey (reminds you which site the password is used for)
Draw your secret pattern (it is never stored anywhere)
The program remembers which password requirements (uppercase, special characters, length) are required by the site.
The program generates your password and copies the password to your clipboard.
You just paste the password wherever you need to use it.
Watch this video which shows how you C'YaPass in action across devices (shown on iPhone and Windows, but it is the same on Android).
