A Travel Clock from the Year of 2000

Yesterday, while searching the office storage room for discontinued products to test for a customer inquiry, I stumbled upon an old travel clock.

解决iPhone(iOS 14.5.1) 无法设置4位数密码的问题

  中年人一直习惯在iPhone上使用4位数锁屏密码,今日却因为在”苹果钱包“中添加“苹果支付”卡片时系统强制将锁屏密码由4位数升级成6位数。最令中年人恼火的是,无法在密码设置菜单中直接将6位锁屏密码变更回4位。 一时间中年人的手指跟脑袋都难以适用这个突然的变化,于是便开始搜寻解决办法。几经尝试最后总算顺利解决,现将方法公布如下: 进入设置菜单 删除(取消)密码 重新添加(设置)密码,添加过程中再利用“密码选项”菜单选择”4位数密码“。
