Firebase允许来自同一电子邮件地址的多个帐户 [英] Firebase Allowing Multiple Accounts from Same Email Address
问题描述
在Firebase控制台中，我专门将其设置为仅允许每个电子邮件地址一个帐户".可以在登录方法选项卡上的高级"下找到.
Within the Firebase console I have specifically set it to only allow "One account per email address". This is found on the sign-in method tab under "advanced".
我有一个使用Google登录方法创建的帐户，其地址类似于"me@gmail.com".如果我随后选择使用也使用"me@gmail.com"的帐户通过Facebook登录，则Firebase允许使用该帐户，但Users实体中的电子邮件地址为空.
I have an account created using the Google login method that has an address like "me@gmail.com". If I then choose to sign-in via Facebook using an account that also uses "me@gmail.com", Firebase is allowing it with the exception that the email address in the Users entity is null.
Firebase文档指出:
The Firebase documentation states:
如果您不允许使用相同电子邮件地址的多个帐户，则 用户无法创建使用Google帐户登录的新帐户 如果已经有一个帐户，则使用电子邮件地址ex@gmail.com 使用电子邮件地址ex@gmail.com和密码登录.
if you don't allow multiple accounts with the same email address, a user cannot create a new account that signs in using a Google Account with the email address ex@gmail.com if there already is an account that signs in using the email address ex@gmail.com and a password.
这是否仅在您尝试直接使用用户名/密码创建Firebase登录而不是通过Facebook和Google这样的两家提供商创建帐户时才算在内?我的印象是，如果发现重复的电子邮件地址，则应拒绝注册/登录.我确实意识到引号中包含和密码"，这让我感到奇怪.
Does this only count if you are trying to create a Firebase login directly with a username/password vs creating an account from two providers like Facebook and Google? I would be under the impression that if it finds a duplicate email address it should reject the registration/login. I do realize the quote states "and a password" which makes me wonder.
