[php] Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted

I recently encountered a SwiftMail error while trying to send a mail through gmail.

 Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted.

I was trying to send mail through my gmail and google thought that I was a spam(maybe because I was requesting too fast) I received a mail from them saying my account was access and I told them it was me. I was able to send mail without problem and it just occured now.

This is the contents of my env file.

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=mypasswordhere
[email protected]
MAIL_NAME=talentscout

I had everything fine. Less secure app option was also enabled. Still, I was getting the error. What I have done is:

• Google will send you Critical security alert
• Then you have to authorize that activity. ( Clicking on 'YES, THAT WAS ME' type thing )
• Then you can try sending email again.

I had the same problem, then I did this two steps:

• Enable "Allow less secure apps" on your google account security policy.
• Restart your local servers.

This is my .env mail settings

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=hello27
MAIL_ENCRYPTION=tls

i was getting thesame error as stated in the question but by using

php artisan config:cache

Everything worked fine

There is no need to update anything in config/mail.php. just put you credential in .env with this specific key's. This is my .env file.

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=********
MAIL_ENCRYPTION=tls

I had the same issue after long time debugging and googling i have found the solution. that by enabling less secure apps. the email started working.

if your gmail is secure with 2 step verification you can't enable less secure app. so turn off 2 step verification and enable less secure app. by click here enable less secure apps on your gmail account

Gmail tends to block usage of mailing addresses which are being used in other applications as username for security reasons. Either you should create a new email address for mail purpose or you must go to the Less Secure App Access and turn on the access for less secure apps. Gmail will send you a mail for confirmation from where you can verify that those changes were made by yourself. Only then, you can use such mailing addresses for mailing purpose through applications.

I had the same problem, changing my gmail password fixed the issue, and also don't forget to enable less secure app on on your gmail account

i had same issue i resolve this use under

go to gmail.com

my account

and enable

Allow less secure apps: ON

it start works

This single step worked for me... No 2-step verification. As I had created a dummy account for my local development, so I was OK with this setting. Make sure you only do this if your account contains NO personal or any critical data. This is just another way of tackling this error and NOT secure.

I turned ON the setting to alow less secured apps to be allowed access. Form here : https://myaccount.google.com/lesssecureapps
