MMoSP003C- steem-python 定制修改密码的工具

一般我们从官网 steemit.com 注册账号,相对比较安全.

密码丢失后(被盗后),可以找 steemit.com 帮助恢复.

当然,能被恢复,就意味着被其他人更改.但steem机制时,如果上一次密码不能提供,则无法恢复.

因此,不管我们的账号是从哪儿获得,连续改两次密码,并保留两次更改的密码,则只能有自己能够恢复密码了,其他人就不能恢复密码.

我们一般登陆 steemit.com,在官方在线钱包中 修改密码,但就比较麻烦,不如直接命令行用工具改.

这里就示范一个修改密码的工具(MMoSP003_customize_a_tools_for_change_keys.py):
