In the PSB portal, why do some email addresses have a plus
Some email addresses in Accounts > Administrators may have a plus sign in the email address. This results from the new authentication back-end that requires a unique email address.
There are two situations where an email address may include a plus sign:
Migration to the new authentication system
During the migration process, if an email address in the old system conflicted with an email address in the new authentication system, a plus sign was added to a number of email addresses to guarantee their uniqueness.
Creation of a new account
When creating a new account, the user may be notified that the email address is already in use. From the end-user's point of view, the same email address can be reused by decorating it as show in the following example: firstname.lastname@example.org -> email@example.com
With the "+" notification, we want to ensure that
emails are received normally as our email gateway will remove the "+abc" part prior to sending the email and hence the user does not need multiple email addresses;
the email address is considered unique in our authentication system.
Note: Our email gateway will strip the "+" part from the email address prior to sending the email. Nothing is affected as long as you keep logging in with your username.
To ensure that you can log in to the PSB portal, always use your username when logging in or when using the "Forgot my password" option.
If you are logging in with your email address, the email address needs to be identical in the new system. In other words, it should include the "+" part if present.
