In addition, the password is marked expired. The user must choose a new one when next connecting. If the plugin requires a hashed string, the string is assumed to be already hashed in the format the plugin requires.
Discards the account secondary password, if there is one, as described previously in this section. Example: Specify the authentication plugin, along with a cleartext password value:.
Example: Like the preceding example, but in addition, specify the current password as a cleartext value to satisfy any account requirement that the user making the change knows that password:. The preceding statement fails unless the current user is jeffrey because REPLACE is permitted only for changes to the current user's password. Example: Establish a new primary password and retain the existing password as the secondary password:.
Example: Discard the secondary password, leaving the account with only its primary password:. Example: Specify the authentication plugin, along with a hashed password value:. For additional information about setting passwords and authentication plugins, see Section 6. In each case, the clause specifies an operation to perform on one authentication factor, and optionally an operation on another authentication factor. For each operation, the factor item specifies the FACTOR keyword preceded by the number 2 or 3 to indicate whether the operation applies to the second or third authentication factor.
See Configuring the Multifactor Authentication Policy. For ADD , each named factor must not already exist or it cannot be added. If a second and third factor are defined, dropping the second factor causes the third factor to take its place as the second factor. This statement drops authentication factors 2 and 3, which has the effect of converting the account from 3FA to 1FA:.
For information about factor-specific rules that determine the default authentication plugin for authentication clauses that do not name a plugin, see The Default Authentication Plugin. These statements are not intended for manual execution. Each role name uses the format described in Section 6. For example:. ALL : Set the default to all roles granted to the account. MySQL can check X.
Indicates that all accounts named by the statement have no SSL or X. Unencrypted connections are permitted if the user name and password are valid. Encrypted connections can be used, at the client's option, if the client has the proper certificate and key files.
Clients attempt to establish a secure connection by default. Tells the server to permit only encrypted connections for all accounts named by the statement. For all accounts named by the statement, requires that clients present a valid certificate, but the exact certificate, issuer, and subject do not matter. The only requirement is that it should be possible to verify its signature with one of the CA certificates. Use of X. It is recommended but not required that --ssl-ca also be specified so that the public certificate provided by the server can be verified.
For all accounts named by the statement, requires that clients present a valid X. If a client presents a certificate that is valid but has a different issuer, the server rejects the connection. If a client presents a certificate that is valid but has a different subject, the server rejects the connection. MySQL does a simple string comparison of the ' subject ' value to the value in the certificate, so lettercase and component ordering must be given exactly as present in the certificate.
For all accounts named by the statement, requires a specific cipher method for encrypting connections. This option is needed to ensure that ciphers and key lengths of sufficient strength are used. Encryption can be weak if old algorithms using short encryption keys are used. It is possible to place limits on use of server resources by an account, as discussed in Section 6. Order of WITH options does not matter, except that if a given resource limit is specified multiple times, the last instance takes precedence.
For all accounts named by the statement, these options restrict how many queries, updates, and connections to the server are permitted to each account during any given one-hour period. If count is 0 the default , this means that there is no limitation for the account.
For all accounts named by the statement, restricts the maximum number of simultaneous connections to the server by each account.
A nonzero count specifies the limit for the account explicitly. Password expiration options: You can expire an account password manually and establish its password expiration policy. Policy options do not expire the password. Instead, they determine how the server applies automatic expiration to the account based on password age, which is assessed from the date and time of the most recent account password change.
Password reuse options: You can restrict password reuse based on number of password changes, time elapsed, or both. Password verification-required options: You can indicate whether attempts to change an account password must specify the current password, as verification that the user attempting to make the change actually knows the current password. Incorrect-password failed-login tracking options: You can cause the server to track failed login attempts and temporarily lock accounts for which too many consecutive incorrect passwords are given.
The required number of failures and the lock time are configurable. This section describes the syntax for password-management options. For information about establishing policy for password management, see Section 6. If multiple password-management options of a given type are specified, the last one takes precedence.
Except for the options that pertain to failed-login tracking, password-management options apply only to accounts that use an authentication plugin that stores credentials internally to MySQL. A client has an expired password if the account password was expired manually or the password age is considered greater than its permitted lifetime per the automatic expiration policy.
In this case, the server either disconnects the client or restricts the operations permitted to it see Section 6. Operations performed by a restricted client result in an error until the user establishes a new account password. DBAs can enforce non-reuse by establishing an appropriate password-reuse policy. See Password Reuse Policy. Immediately marks the password expired for all accounts named by the statement.

If you are not logged in as mysql the user the server runs as , make sure that the file has permissions that permit mysql to read it.
Other options may be necessary as well, depending on how you normally start your server. Stop the server and restart it normally. The preceding sections provide password-resetting instructions specifically for Windows and Unix and Unix-like systems. Alternatively, on any platform, you can reset the password using the mysql client but this approach is less secure :. Stop the MySQL server if necessary, then restart it with the --skip-grant-tables option.
Connect to the MySQL server using the mysql client; no password is necessary because the server was started with --skip-grant-tables :. In the mysql client, tell the server to reload the grant tables so that account-management statements work:. Then change the 'root' 'localhost' account password. InnoDB Cluster. InnoDB ReplicaSet.
