 > [!IMPORTANT]
 > Parse Server does not keep a history of verification tokens but only stores the most recently generated verification token in the database. Every time Parse Server generates a new verification token, the currently stored token is replaced. If a user opens a link with an expired token, and that token has already been replaced in the database, Parse Server cannot associate the expired token with any user. In this case, another way has to be offered to the user to re-send a verification email. To mitigate this issue, set the Parse Server option `emailVerifyTokenReuseIfValid: true` and set `emailVerifyTokenValidityDuration` to a longer duration, which ensures that the currently stored verification token is not replaced too soon.

+## Database Indexes
+
+As part of the email verification and password reset improvements in Parse Server 8, the queries used for these operations have changed to use tokens instead of username/email fields. To ensure optimal query performance, Parse Server now automatically creates indexes on the following fields during server initialization:
+
+- `_User._email_verify_token`: used for email verification queries
+- `_User._perishable_token`: used for password reset queries
+
+These indexes are created automatically when Parse Server starts, similar to how indexes for `username` and `email` fields are created. No manual intervention is required.
+
+> [!WARNING]
+> If you have a large existing user base, the index creation may take some time during the first server startup after upgrading to Parse Server 8. The server logs will indicate when index creation is complete or if any errors occur. If you have any concerns regarding a potential database performance impact during index creation, you could create these indexes manually in a controlled procedure before upgrading Parse Server.
