I think a web-based wallet like MEW is vulnerable to steal by the hacker, and javvy answers the problem by creating a non-web-based application wallet. but I'm hampered making passwords when signing up, I've used the combination of uppercase and symbol @ and # but failed, so what symbols are accepted?
Hi Andriw,
You are correct that it's a bit strict. The desktop version makes this clear. In a future version of the mobiles (iOS and Android), the login UI will be polished to show the requirements and "check them off" as you meet them. For now, just know that it's a bit of everything: so at least 1 uppercase, at least 1 lowercase, at least 1 numeric, and at least 1 symbol... and I believe there is an 8-character minimum as well.
We're glad you see the benefit of app-based vs web-based... this is what we believe is the future of crypto!

Cheers,
Brandon
