Password plaintext

Hi,

Great software.

Can we please change it so the password is not displayed in plain text in the settings? Also, the ability to upload to multiple user profiles would be amazing.

Most of what I want to share goes to my personal account, but occasionally I'd like to share something with a link (sharex folder). Being able to pick somehow would be great.

Thanks.

查找显示密码的 Settings activity 或 fragment。密码字段应改为使用能够遮罩文本的输入类型，例如 `InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD`。对于多 profile 支持，请检查当前如何配置和存储上传目标。检查是否存在可扩展的 profile 管理或账户切换 UI 组件。
