首先，淘宝是没有支付密码的，我们在使用淘宝购物时，是使用同属阿里巴巴体系的支付宝来进行支付。以下是修改支付宝支付密码的具体操作：
1.打开支付宝，登录之后，先点击底部的最右侧图标打开“我的”。

2.然后选择右上角的“设置”。

3.进入设置后再点击“密码设置”，进入下一个页面。

https://iknow-pic.cdn.bcebos.com/a71ea8d3fd1f41346763888f291f95cad0c85eef"/>
4.选择“重置支付密码”。

https://iknow-pic.cdn.bcebos.com/d53f8794a4c27d1edc4db63517d5ad6edcc438d3"/>
5.此时支付宝会检查安全状况，建议在经常使用此账号的手机上进行操作，并避免在公共网络上重置密码。这个页面只有两个选项，若是还记得当前密码，就选择“记得”。

https://iknow-pic.cdn.bcebos.com/dc54564e9258d10952cd2443dd58ccbf6c814d11"/>
6.然后，系统会提示输入一个新密码，这里需要输入两次。

7.完成后点击下一步即可完成修改。

8.若是不记得当前密码，那在第5步就像图中一样选择不记得，然后就需要用到绑定的手机来接收一条验证码。

9.正确的输入验证码，然后系统会自动跳转到下一个页面。

10.在输入框中输入注册人的身份证号码。
