I have forgotten my Oracle username and password and hence not able to use it. My Oracle version is 11.2.0.1.0(11g). I consulted Internet. They asked me to execute commands like ‘SYSDBA’ but I was unable to do it as once I give ‘SYSDBA’ on Command Prompt screen, it takes the command as the username and next asks for password. I cannot execute any commands suggested by them as whatever I enter is taken as the username, subsequently password is asked and error occurs.
Open your SQL command line and type the following:
SQL> connect / as sysdba
Once connected,you can enter the following query to get details of username and password:
SQL> select username,password from dba_users;
This will list down the usernames,but passwords would not be visible.But you can identify the particular username and then change the password for that user.
For changing the password,use the below query:
SQL> alter user username identified by password;
Here username is the name of user whose password you want to change and password is the new password.
Go to SQL command line:-
type:
sql>connect / as sysdba;
then type:
sql>desc dba_users;
then type:
sql>select username,password from dba_users;
If sysdba doesn't work then try connecting with username:scott and password: Tiger
You will be able to see all users with passwords.
Probably you might find your's.
Hope this helps
Open Command Prompt/Terminal and type:
sqlplus / as SYSDBA
SQL prompt will turn up. Now type:
ALTER USER existing_account_name IDENTIFIED BY new_password ACCOUNT UNLOCK;
Voila! You've unlocked your account.
The usernames are shown in the dba_users's username column, there is a script you can run called:
alter user username identified by password
You can get more information here - https://community.oracle.com/thread/632617?tstart=0
if you are on Windows
Start the Oracle service if it is not started (most probably it starts automatically when Windows starts)
Start CMD.exe
in the cmd (black window) type:
sqlplus / as sysdba
Now you are logged with SYS user and you can do anything you want (query DBA_USERS to find out your username, or change any user password). You can not see the old password, you can only change it.

I am using gAdmin on mac. So far I have not been able to figure out how to run the desktop version, so I am running the web application. I want to change the password for the user postres. The reason being, I am trying to connect R to postres using:
db <- 'dvdrental' #provide the name of your db
host_db <- "localhost"
db_port <- '5432'
db_user <- "postgres"
db_password <- " " # I typed the master password in, as I do not remember setting up this user/password
con<-dbConnect(RPostgres::Postgres(), dbname = db, host=host_db, port=db_port, user=db_user, password=db_password)
but I keep getting below error:
Error: FATAL: password authentication failed for user "postgres".
This is thee reason for the change of password for the user postgres
How can I change a user password in PgAmin4 using webapp on mac?
In PgAdmin4, if you are changing the password for the same user you are logged in as, then you need to select a connected database from the browser tree. Once you do that, the "Object" menu "Change Password..." option.
If you are logged into the server as a super user and want to change the password of a different user/role, then right click (or whatever mac uses for that function) on that user/role from the tree and choose "Properties...". Then under the "definition" tab there is a place to enter the new password. Note that this method is inferior, as the password is received by the server as plain text (once any ssl decryption is done) and so can end up in the log file in the clear.
Why constrain yourself to PgAdmin4? psql has \password, which does this better.
I am on windows using Xampp
I want to upload a file on shiny, but I receive this error; Access denied for user 'myusername'#'localhost' (using password: YES)
This is what I have in R:
mysql = list(
"host" = "127.0.0.1",
"port" = 3306,
"user" = "myuser",
"password" = "mypassword"
“databaseName" = "xxx"),
Could someone tell me how to fix it?
Thanks a lot
You could create a user specially for your shiny application and give this user proper privileges. If you can access a terminal / MySQL workbench where you can type in SQL commands you could try:
Start by creating the user:
CREATE USER 'shinyuser'#'%' IDENTIFIED BY 'password123';
The create the database if necessary:
CREATE DATABASE MyDatabase;
And finally give permission to the new user:
GRANT ALL PRIVILEGES ON shinyuser.* TO 'MyDatabase'#'%' WITH GRANT OPTION;
This problem arises when your username and password is not matching with your database username and password. So please check your database username and password first then try it again.
I'm trying to create an extranet user within sitecore but i'm having issues. I'm using the command Membership.CreateUser(username, password, email)
Nothing seems to happen though. No user is created in the extranet aspnetdb. No exceptions are thrown.
I also tried putting the domain as part of the user name: domain\username...and I get the error "You must specify a non-autogenerated machine key to store passwords in encrypted format. Either specify a different passwordFormat, or change the machineKey configuration to use a non-autogenerated decryption key.". My passwordFormat is Encrypted.
Any ideas what i'm doing wrong?
Thanks in advance.
Did you try what the error message suggested? I would try setting your own Machine Key. More about that here. As always, do this in a test/dev environment.
You can use below code -
uname = string.Format(#"{0}{1}", domain, userName);
Membership.CreateUser(uname, password, email);
I can't figure out how to change the webdav password. I've done some searching, found many resources of how to add a new user to webdav, but nothing about changing password. Anyone know?
Passwords are stored in webdav.htpasswd file.
If you open it, you will see an entry like this
wampp:XAMPP with WebDAV:bc7f2b670e7e965e307feb30492e642e
That's the entry for user wampp: in realm XAMPP with WebDAV: with password which is encrypted.
To change password, you should use htdigest.exe.
See manual. It is used to create and update user authentication files. You should find in the bin directory of xampp installation.
To do that, do :
htdigest.exe "pathto/webdav.htpasswd" "XAMPP with WebDAV" yourusername
This will be returned:
Adding user yourusername in realm "XAMPP with WebDAV"
You will then be asked for the password for yourusername
New password: yourpassword
Re-type new password: yourpassword
Reference: http://www.apachefriends.org/f/viewtopic.php?f=16&t=38897
Replace the content of the file C:\Program Files\xampp\security\htpasswd.webdav with your username, a colon and the password. Note: Everyone who can see this file can see the password!
Assuming you're talking about doing a password change at the server from a client, I don't believe WebDAV supports such a transaction.
You'd use something like a shell logon or a Web-based admin page to do this.
This always struck me as odd for a lot of network services, for example FTP or email. It seems to be common though.
i forgot my drupal user id and password. Is there any way to recover it
http://example.com/<path-to-drupal>/user/password should bring you to a page where you can request a reset/new-password.
Edit:
The above path applies if you have 'clean URLs' enabled, if not use http://example.com/<path-to-drupal>/?q=user/password
This solution is valid for Drupal 5 or 6 but not for Drupal 7. This version does not use a standard hashed password. You can get your encoded password running the following command:
php /path_to_drupal_files/scripts/password-hash.sh your_password
Then you can see your password hash. This is the string that you should use in the database to update the admin password. You can use the following SQL query to update the Drupal database.
UPDATE users SET pass='YOUR_PASSWORD_HASH' where uid=1;
If you don't have access to the email (or want to bulk-update the passwords) you can update the database with a query like:
UPDATE users SET pass = md5('NEWPASSWORD') WHERE name = 'admin'
